When calling solid with passing argument getting this error

Question

When calling solid with passing argument getting this error So initial argument can not be passed directly it always needs to return from another solid How to pass dynamic value to solid in that case Can some one help me I am newbie so sorry for such silly question ```download file file path ```

Hi Keval if you want to execute a single solid you can use `<https docs dagster io apidocs execution dagster execute solid>` which accepts a dynamic value Do you need to execute a full pipeline on dynamic inputs This is a little bit more involved

Hi < sandy> Thanks for your reply I want to execute pipeline and first solid I want to send data as argument Do you suggest any example for it thanks in advance

< alex> do you happen to know whether the graph refactor makes this easier

alex · Answer

you ld be able to set the default value for the input definition on the graph could will map in to the solid but that would be a fixed value for that graph for now you should be able to provide that value via the run config for a run of that pipeline would look like this ```solids download file inputs link lt the link gt ```

from the error message gt solid get url decorated function does not have required positional parameter context Solid functions should only have keyword arguments that match input names and a first positional parameter named context the first parameter to your ` solid` functions need to be `context` followed by ones you want for parameters You can use ` ` instead if you don t need to use anything on the `context`
