I have several tasks where I call out to the shell using subprocess. When I

flow.run()

locally, I see all the stdout information from these subprocesses in the prefect log output. But I do not see the same information in prefect cloud. Is there a configuration setting or something I can update to ensure I see this output in the cloud logs?

Yep that would be the way of getting that information to cloud. Cloud only takes in logs sent through the prefect logger and not anything which is generally printed to stdout

This makes me think the Docker container running your flows has an older version of Prefect, as we log all stdout lines from the subprocess now: https://github.com/PrefectHQ/prefect/blob/master/src/prefect/tasks/shell.py#L103
