asset requires a resource with the key 'sio'
, but this resource was not provided in the job's resource_defs
. The error message also suggests that you should provide a ResourceDefinition
for the key 'sio'
, or change the required key to one of the keys that is actually provided. In your all_assets_job
, you are defining resource_defs
using patch_cloud_storage_selector
and passing a dictionary that includes "sio": socket_resource
. This suggests that the socket_resource
should be available to your assets with the key 'sio'
. However, if the error persists, it could be due to several reasons: 1. The socket_resource
may not be correctly defined or may not be a ResourceDefinition
. 2. There might be an issue with how the patch_cloud_storage_selector
function is handling the resources. 3. The socket_resource
may not be correctly configured or instantiated when the job is executed. To debug this issue, you can: - Ensure that socket_resource
is a valid ResourceDefinition
and is correctly configured. - Verify that the patch_cloud_storage_selector
function is correctly applying the resource definitions to the job. - Check if there are any typos or mismatches in the resource keys between the asset definitions and the job's resource_defs
. - Make sure that the socket_resource
is accessible and properly initialized at runtime. If you've checked all of the above and the issue still occurs, you may need to look into the implementation details of the patch_cloud_storage_selector
function and the socket_resource
to ensure they are compatible with the job and asset definitions. Remember that the resources you define in resource_defs
for a job must match the required_resource_keys
specified in your assets. If there's a mismatch, Dagster will not be able to resolve the required resources, leading to the error you're seeing.SUBHADEEP ROY

you're encountering, you should ensure that the resources required by your assets are correctly provided in the job's resource_defs
. Here are some steps you can take to debug and resolve the issue: 1. Check Resource Definitions: Ensure that socket_resource
and other resources are correctly defined and that they inherit from ResourceDefinition
. The resources should be available and correctly configured to be used by the assets. 2. Verify Resource Keys: Make sure that the keys used in required_resource_keys
within your asset definitions exactly match the keys provided in the resource_defs
of your job. In your case, the show_schema_asset
asset requires a resource with the key 'sio'
, so you must provide a resource with that exact key in the job's resource_defs
. 3. Review Resource Selector Function: If you are using a custom function like patch_cloud_storage_selector
to define your resources, ensure that this function is correctly applying the resource definitions. It should return a dictionary where the keys match the required_resource_keys
of your assets. 4. Check Resource Availability: When the job is executed, the resources must be correctly instantiated and available for the assets. If there's an issue with the instantiation or configuration of the resources at runtime, it could lead to the error you're seeing. 5. Simplify for Testing: As a debugging step, you might want to simplify your job definition to include only the show_schema_asset
asset and the minimal set of resources required. This can help isolate the issue. 6. Consult Documentation and Examples: Review the Dagster documentation for examples of defining resources and providing them to jobs. Ensure that your implementation follows the documented patterns. 7. Error Messages and Logs: Pay close attention to the error messages and logs when you execute the job. They can provide clues about what might be going wrong. 8. Update and Retry: After making changes to your resource definitions or job configuration, make sure to update your repository and retry executing the job to see if the issue is resolved. If you've gone through these steps and the issue persists, you might want to provide more details about the socket_resource
and the patch_cloud_storage_selector
function, as the problem could be specific to their implementations.Scout
03/09/2024, 8:10 AMDagsterInvalidDefinitionError: Conflicting versions of resource with key 'dw_obj' were provided to different assets
, indicates that there are conflicting resource definitions for the resource key 'dw_obj'
being used by different assets within the same job. In Dagster, when you construct a job that includes multiple assets, each resource key must point to a single resource definition. If different assets within the same job provide different definitions for the same resource key, Dagster will raise an error because it cannot determine which definition to use. To resolve this issue, you need to ensure that the resource with the key 'dw_obj'
is defined once and that the same definition is used by all assets that require it. Here's how you can approach fixing this: 1. Consolidate Resource Definitions: Make sure that you define the resource with the key 'dw_obj'
only once and use the same definition for all assets that require it. 2. Check Resource Selector Functions: If you are using a function like warehouse_resource_selector()
to get the resource definition, ensure that this function always returns the same resource instance for the 'dw_obj'
key. If this function returns different instances (perhaps due to different configurations or parameters), it will lead to the error you're seeing. 3. Review Job Resource Definitions: In your all_assets_job
, you should provide a single, consistent set of resource definitions that will be used by all assets included in the job. This means that the resource_defs
dictionary should have one entry for each unique resource key, and the corresponding value should be the same resource definition used by all assets that require that key. 4. Update Asset Decorators: Update the @asset
decorators for all assets to ensure they are not providing conflicting resource definitions. They should all reference the same resource instances provided in the job's resource_defs
. 5. Test with a Simplified Job: As a debugging step, you can create a simplified job that includes only one asset and the minimal set of resources required. Once that works, gradually add more assets to the job, ensuring that the resource definitions remain consistent. 6. Execute and Verify: After making the necessary changes, execute the job again and verify that the error is resolved. By following these steps, you should be able to resolve the DagsterInvalidDefinitionError
and ensure that your job executes successfully with consistent resource definitions.SUBHADEEP ROY

regarding conflicting resource definitions for the key 'dw_obj'
, you should ensure that the resource is defined once and used consistently across all assets. Here's a step-by-step guide to refactor your code: 1. Define Resources Once: Define your resources in one place. For example, you can create a function that returns all the resources you need: python def define_resources(): return { "sio": socket_resource, "db_obj1": metadata_resource, "dw_obj": warehouse_resource_selector(), # Add other resources as needed }
2. Use Defined Resources in Assets: Use the resources from the function you defined in your assets. For example: python @asset(resource_defs=define_resources()) def show_schema_asset(context) -> pd.DataFrame: # Your asset code here pass @asset(resource_defs=define_resources()) def show_table_asset(context) -> pd.DataFrame: # Your asset code here pass
3. Use Defined Resources in Job: Use the same resources in your job definition: python @job(resource_defs=define_resources()) def all_assets_job(): show_schema_asset() show_table_asset() # Include other assets as needed
4. Repository Definition: Update your repository definition to include the refactored job and assets: python @repository def my_repo(): return [ show_schema_asset, show_table_asset, # Include other assets as needed all_assets_job, ]
5. Execute and Verify: After refactoring, execute the job again to verify that the error is resolved: python if __name__ == "__main__": result = my_repo.get_job("all_assets_job").execute_in_process() if not result.success: raise Exception("Asset job execution failed")
By following these steps, you should be able to refactor your code to resolve the conflicting resource definitions. Remember to replace the placeholders with your actual asset code and ensure that the define_resources
function returns consistent resource instances for the 'dw_obj'
key and any other resources your assets require.SUBHADEEP ROY

provided to different assets. This can happen if the function warehouse_resource_selector()
returns different instances of the resource each time it is called, rather than a single, consistent instance. To ensure that the same instance of the resource is used across all assets, you can instantiate the resource once and then pass that instance to the assets and job. Here's how you can modify your define_resources
function to achieve this: python def define_resources(): # Instantiate the resources once sio_instance = socket_resource() db_obj1_instance = metadata_resource() dw_obj_instance = warehouse_resource_selector() # Return a dictionary of the instantiated resources return { "sio": sio_instance, "db_obj1": db_obj1_instance, "dw_obj": dw_obj_instance, # Add other resources as needed }
By doing this, you ensure that the same instance of each resource is used consistently across all assets and the job. This should resolve the DagsterInvalidDefinitionError
related to conflicting resource versions. Make sure to update your assets and job to use the define_resources
function as shown in the previous example: python @asset(resource_defs=define_resources()) def show_schema_asset(context) -> pd.DataFrame: # Your asset code here pass # Repeat for other assets... @job(resource_defs=define_resources()) def all_assets_job(): show_schema_asset() show_table_asset() # Include other assets as needed
After making these changes, try executing the job again to see if the issue is resolved. If the error persists, double-check that the warehouse_resource_selector()
function does not create a new instance each time it is called, and ensure that all assets and the job are using the define_resources
function to obtain their resources.SUBHADEEP ROY

03/09/2024, 8:31 AMDagsterInvalidInvocationError: Resource initialization function has context argument, but no context was provided when invoking
indicates that a resource initialization function expects a context object, but it was not provided during the invocation of the resource. This error typically occurs when you are trying to directly instantiate a resource that requires a context object for its initialization, outside of the Dagster-managed environment where the context would be automatically provided. To resolve this issue, you should use Dagster's resource initialization APIs to create instances of your resources. These APIs manage the context for you. For testing or creating resources outside of a Dagster pipeline execution, you can use build_init_resource_context
to construct a context that can be passed to the resource initialization function. Here's an example of how you might use `build_init_resource_context`: python from dagster import build_init_resource_context def define_resources(): # Create a context for resource initialization with build_init_resource_context() as context: # Instantiate the resources with the context sio_instance = socket_resource(context) db_obj1_instance = metadata_resource(context) dw_obj_instance = warehouse_resource_selector(context) # Return a dictionary of the instantiated resources return { "sio": sio_instance, "db_obj1": db_obj1_instance, "dw_obj": dw_obj_instance, # Add other resources as needed }
Please note that the above code is just an example, and the actual implementation may vary based on how your resources are defined and what arguments their initialization functions expect. If your resources do not require any specific context for initialization, you might be able to use build_resources
to build them directly: python from dagster import build_resources def define_resources(): # Instantiate and return the resources using build_resources return build_resources({ "sio": socket_resource, "db_obj1": metadata_resource, "dw_obj": warehouse_resource_selector, # Add other resources as needed })
Again, please adjust the code to fit your specific resource definitions and initialization requirements. After making these changes, try executing the job again to see if the issue is resolved. If you continue to encounter problems, please ensure that your resource definitions and their initialization functions are correctly implemented according to the documentation.SUBHADEEP ROY

that can be used by assets during execution. Specifically, you can provide run_config
, resources
, and tags
as parameters to configure the execution environment for the job. Here's how you can pass these parameters: - `run_config`: This is a dictionary that specifies the configuration for the run. It can include configurations for resources, loggers, and any other configurable components of the job. - `resources`: This is a dictionary that allows you to override the resources defined in the job with new instances or configurations. This can be useful for testing or when you want to provide different resource implementations. - `tags`: This is a dictionary of string key-value pairs that allows you to attach metadata to the run. Tags can be used for filtering and organizing runs in the Dagster UI. Here's an example of how you might use execute_in_process()
with these parameters: python result = my_repo.get_job("all_assets_job").execute_in_process( run_config={ "solids": { "my_solid": { "config": { "param1": "value1", "param2": "value2", } } } }, resources={ "my_resource": my_resource_instance, }, tags={ "key1": "value1", "key2": "value2", } )
In this example, run_config
provides configuration for a hypothetical solid called my_solid
, resources
provides a new instance of my_resource
, and tags
adds metadata to the run. Please adjust the run_config
, resources
, and tags
according to your job's and assets' specific requirements. The keys and structure of the run_config
dictionary will depend on the configuration schema defined by your job and its components. Keep in mind that when using execute_in_process
, the executor_def
on the job will be ignored, and replaced with the in-process executor. If using the default io_manager
, it will switch from filesystem to in-memory. This is important to consider if your assets rely on specific IO behavior.SUBHADEEP ROY

within an @asset
, you need to ensure that your asset function is set up to require the resources by specifying required_resource_keys
. Then, within the body of the asset function, you can access the resources through the context
object. Here's an example of how you might define an asset that requires db_obj
and dw_obj
resources: python from dagster import asset, ResourceDefinition # Define your resources as ResourceDefinitions if not already done db_obj_resource = ResourceDefinition.hardcoded_resource(db_obj) dw_obj_resource = ResourceDefinition.hardcoded_resource(dw_obj) # Define your asset with required_resource_keys @asset(required_resource_keys={"db_obj", "dw_obj"}) def my_asset(context): # Access the resources from the context db = context.resources.db_obj dw = context.resources.dw_obj # Use the resources as needed db_data = db.get_data() dw_data = dw.get_data() # Your asset logic here combined_data = db_data + dw_data return combined_data
When you execute the job in process and pass the resources, the db_obj
and dw_obj
inside the context will be the instances you provided: python result = my_repo.get_job("all_assets_job").execute_in_process( resources={ "db_obj": db_obj_resource, "dw_obj": dw_obj_resource, } )
Please note that in the execute_in_process
call, you should pass instances of ResourceDefinition
for db_obj
and dw_obj
. If db_obj
and dw_obj
are already instances of ResourceDefinition
, you can pass them directly; otherwise, you need to wrap them using ResourceDefinition.hardcoded_resource
. Make sure that the keys you use in required_resource_keys
for your assets match the keys you use in the resources
dictionary when executing the job. This ensures that the correct resources are injected into the asset's context during execution.Scout

, you are overriding the resources defined in the job's resource_defs
. To use these resources within an @asset
, you need to ensure that the asset has the appropriate required_resource_keys
set, and then you can access the resources via the context
object provided to the asset function. Here's an example of how you might define an asset that uses the db_obj
and dw_obj
resources: python from dagster import asset @asset(required_resource_keys={"db_obj", "dw_obj"}) def my_asset(context): # Access the resources from the context db_resource = context.resources.db_obj dw_resource = context.resources.dw_obj # Use the resources as needed result_from_db = db_resource.some_method() result_from_dw = dw_resource.another_method() # Return the result of your asset computation return result_from_db, result_from_dw
In this example, some_method
and another_method
are placeholder methods that you would replace with the actual methods provided by your db_obj
and dw_obj
resources. When you execute the job with execute_in_process
and provide the resources as shown in your example, the db_obj
and dw_obj
passed at execution time will be used by the asset during its computation: python result = my_repo.get_job("all_assets_job").execute_in_process( resources={ "db_obj": db_obj, "dw_obj": dw_obj, } )
Make sure that the keys used in the required_resource_keys
of your asset match the keys you are passing in the resources

asset requires a resource with the key 'db_obj'
, but this resource was not provided when invoking the job. The error message also suggests that you should provide a ResourceDefinition
for the key 'db_obj'
. Looking at your code, there are a few issues that need to be addressed: 1. The required_resource_keys
in the show_schema_asset
asset function is set to {"db_obj", "dw_obj"}
, but within the function, you are trying to access db_obj1
instead of db_obj
. You need to correct the key to match the required resource keys. 2. You are passing instances of db_obj
and dw_obj
directly to execute_in_process
, but Dagster expects ResourceDefinition
objects, not instances. You need to ensure that the resources you pass to execute_in_process
are wrapped in a ResourceDefinition
or are callable functions that return the resource instance when invoked by Dagster. 3. The @job
decorator is empty. If you have specific resources that need to be associated with the job, you should define them in the resource_defs
argument of the @job
decorator. Here's how you can refactor the show_schema_asset
function to use the correct resource keys: python @asset(required_resource_keys={"db_obj", "dw_obj"}) def show_schema_asset(context) -> pd.DataFrame: db_obj = context.resources.db_obj # Use 'db_obj' instead of 'db_obj1' dw_obj = context.resources.dw_obj # ... rest of your code ...
To pass the resources to execute_in_process
, you need to wrap them in ResourceDefinition
if they are not already. If db_obj
and dw_obj
are functions that return the resource instance, you can use them directly. Otherwise, you'll need to create a ResourceDefinition
that returns the instance. Here's an example of how you might do this: python from dagster import resource # Assuming db_obj and dw_obj are functions that return the resource instance db_obj_resource = resource(db_obj) dw_obj_resource = resource(dw_obj) result = my_repo.get_job("all_assets_job").execute_in_process( resources={ "db_obj": db_obj_resource, "dw_obj": dw_obj_resource, } )
Make sure to adjust the resource
definitions according to how your db_obj
and dw_obj
are implemented. After making these changes, try executing the job again to see if the issue is resolved. If you continue to encounter problems, please ensure that your resource definitions and their initialization functions are correctly implemented according to Dagster's documentation.SUBHADEEP ROY

In this example, my_asset
is an asset that requires a config with a key param
. The param
is a string that you can provide when you execute the job. To provide the config when executing the job, you can use the run_config
parameter in `execute_in_process`: python result = my_repo.get_job("all_assets_job").execute_in_process( run_config={ "ops": { "my_asset": { "config": { "param": "my_string_value" } } } } )
In the run_config
, under the ops
key, you specify the name of the asset (which is the same as the function name by default) and provide the config for it. The param
key inside the config
dictionary is where you pass the string value you want to use in the asset. Please adjust the asset name in the run_config
