Hi! I have a Prefect flow that runs successfully and returns a

Flow Run Succeeded

but the process doesn’t exit after success and instead hangs. Any idea what’s happening?

Hi @Sophia Alice! Where are your flows running? and what do the agent logs look like?

Hi @Nate! Flows are running locally (local for me is a MBP with an Intel chip) and here is one of the logs:

Flow run succeeded!

hmm, where do you notice that the flow is hanging?

After the flow should be done. There’s another process that’s supposed to run after and it never starts. It looks like this in the terminal. it’ll stay like this until I hit ^C

Do you mind sharing the logs where you ran

prefect agent start -q yourqueue

if possible? These appear to be the flow run logs those might give us more info on whether or not the process exited cleanly / what went wrong
