I'm getting

dagster._core.errors.DagsterInvariantViolationError: Attempting to access run_id, but it was not provided when constructing the OutputContext

after switching from multi-processing to in_process execution. The job runs without error in multi-processing; and I've obviously had to switch to

io_manager: mem_io_manager

too. Any ideas on how to debug this?

Hi Jeremy - how are you executing this? With

execute_in_process

? From the UI?

From the UI, but I think I figured it out a bit. I was using Assets converted to SourceAssets. It would run once I replaced those with their corresponding graphs.
