The error you're encountering,
dagster._core.errors.DagsterSubprocessError
, indicates that there were issues during the multiprocess execution of your job. Specifically, the error
dagster._check.CheckError: Invariant failed.
suggests that an internal assertion within Dagster has failed. From the stack trace, it appears that the error is related to the
compute_log_manager
within the Dagster instance. The
compute_log_manager
is responsible for handling logs produced by the execution of steps within a job. The error is raised when the code checks whether the GCS bucket, which is supposed to store the compute logs, exists. Here's the relevant part of the stack trace:
Copy code
python File "/usr/local/lib/python3.11/dist-packages/dagster_gcp/gcs/compute_log_manager.py", line 88, in __init__     check.invariant(self._bucket.exists())
This line is checking that the GCS bucket configured for storing compute logs actually exists. The
CheckError
is thrown because this invariant check fails, meaning the bucket does not exist or is not accessible. To resolve this issue, you should: 1. Verify that the GCS bucket specified for your compute logs is correctly configured and exists. 2. Ensure that the Dagster instance has the necessary permissions to access and write to the GCS bucket. 3. Check that the GCS bucket name and any related configuration settings are correct in your Dagster instance configuration. If after checking these points the issue persists, you may want to look into the following: - Review the configuration of your
compute_log_manager
to ensure it is set up correctly. - Check for any network issues that might be preventing access to the GCS bucket. - Review the IAM permissions for the service account used by Dagster to interact with GCS to ensure it has the necessary roles and permissions. If you need further assistance, you might want to provide more context or configuration details, which could help in diagnosing the problem more accurately.

The error message you're seeing,
dagster._core.errors.SensorExecutionError
, indicates that there was an error during the execution of the evaluation function for your sensor named
dbt_job_fail
. The
CheckError: Invariant failed.
suggests that an internal assertion within Dagster has failed, similar to the previous error you encountered. The stack trace points to an issue with the
compute_log_manager
again, specifically related to the Google Cloud Storage (GCS) bucket that is supposed to store the compute logs. The error is raised when the code checks whether the GCS bucket exists and is accessible. Here's the relevant part of the stack trace:
Copy code
python File "/usr/local/lib/python3.11/dist-packages/dagster_gcp/gcs/compute_log_manager.py", line 88, in __init__     check.invariant(self._bucket.exists())
This line is checking that the GCS bucket configured for storing compute logs actually exists. The
CheckError
is thrown because this invariant check fails, meaning the bucket does not exist or is not accessible. To resolve this issue, you should: 1. Verify that the GCS bucket specified for your compute logs is correctly configured and exists. 2. Ensure that the Dagster instance has the necessary permissions to access and write to the GCS bucket. 3. Check that the GCS bucket name and any related configuration settings are correct in your Dagster instance configuration. If after checking these points the issue persists, you may want to look into the following: - Review the configuration of your
compute_log_manager
to ensure it is set up correctly. - Check for any network issues that might be preventing access to the GCS bucket. - Review the IAM permissions for the service account used by Dagster to interact with GCS to ensure it has the necessary roles and permissions. Since the error is occurring within the sensor execution, it's also possible that there's an issue with how the sensor is configured or how it's interacting with the
compute_log_manager
. If the sensor is supposed to trigger based on logs or events in GCS, make sure that the sensor's logic is correctly implemented and that it's using the correct GCS bucket and path. If you need further assistance, you might want to provide more context or configuration details, which could help in diagnosing the problem more accurately.

@Scout How can I verify the configuration of my compute_log_manager ?

To verify the configuration of your
compute_log_manager
, you should review your Dagster instance's
dagster.yaml
configuration file. This file contains the settings for your Dagster instance, including the compute log manager configuration. Here's what you should do: 1. Locate your
dagster.yaml
file. By default, this file is located in the
DAGSTER_HOME
directory, which is an environment variable that points to the directory where Dagster stores instance-level configuration and data. 2. Open the
dagster.yaml
file and look for the
compute_logs
section. This section defines the configuration for the compute log manager. 3. Verify that the
compute_logs
section is correctly configured for the
GCSComputeLogManager
. The configuration should specify the GCS bucket and any other necessary settings. Here's an example of what the
compute_logs
section might look like for a GCS compute log manager:
Copy code
yaml compute_logs:   module: dagster_gcp.gcs.compute_log_manager   class: GCSComputeLogManager   config:     bucket: "my-gcs-bucket-name"     local_dir: "/path/to/local/dir"     prefix: "my-log-prefix"
In this example, replace
"my-gcs-bucket-name"
with the actual name of your GCS bucket, and adjust the
local_dir
and
prefix
as needed. 4. If you're using environment variables to configure the
compute_log_manager
, ensure that these environment variables are set correctly in the environment where your Dagster instance is running. 5. After verifying or updating the configuration, save the
dagster.yaml
file and restart any Dagster processes (e.g., Dagit, Dagster daemon) to ensure that the changes take effect. 6. Ensure that the GCS bucket specified in the configuration exists and that the Dagster instance has the necessary permissions to access it. If you've verified the configuration and the issue persists, you may want to check the logs for any additional error messages that could provide more insight into the problem. Additionally, you can check the Dagster documentation for more details on configuring the
GCSComputeLogManager
and ensure that all required settings are correctly specified.

Based on the snippet you've provided from your
dagster.yaml
file, it looks like you have configured the
GCSComputeLogManager
to use a GCS bucket named
automotive-dagster-compute-logs
with a prefix of
dagster-compute-logs
for your compute logs. Here are a few steps to ensure that your configuration is correct and to troubleshoot any issues: 1. Bucket Name: Confirm that the bucket name
automotive-dagster-compute-logs
is correct and that the bucket exists in your Google Cloud Storage. 2. Permissions: Make sure that the service account or credentials used by Dagster have the necessary permissions to read from and write to the specified GCS bucket. 3. Prefix: The prefix
dagster-compute-logs
is used to organize logs within the bucket. Verify that this is the desired prefix and that it doesn't conflict with any other resources in the bucket. 4. Environment Variables: If your configuration relies on environment variables for credentials (not shown in the snippet), ensure that these are set correctly in the environment where Dagster is running. 5. Syntax: The configuration block should be correctly indented and formatted as YAML. The snippet you provided seems to have an extra level of nesting under
gcsComputeLogManager
, which might not be necessary. The documentation suggests a slightly different format:
Copy code
yaml compute_logs:   module: dagster_gcp.gcs.compute_log_manager   class: GCSComputeLogManager   config:     bucket: "automotive-dagster-compute-logs"     prefix: "dagster-compute-logs"
6. Restart Dagster: After making any changes to the
dagster.yaml
file, you need to restart your Dagster processes to apply the new configuration. 7. Check for Errors: If you continue to encounter errors, check the Dagster logs for any error messages that could provide more insight into the problem. If you've gone through these steps and the issue persists, you may want to consult the Dagster documentation for more detailed information on configuring the
GCSComputeLogManager
or reach out to the Dagster community for further assistance.
