@Josh: I’m trying to run a Prefect Flow on a Docker Agent. The agent is able to pull the image and complete the deployment of the flow run. The flow progresses from Scheduled to Submitted state in the UI. But there is no docker container that is ever spun up and the agent doesn’t do anything. Is there a checklist similar to this, but for submitted state? https://discourse.prefect.io/t/why-is-my-flow-stuck-in-a-scheduled-state/73
Prefect Community: Why is my flow stuck in a Scheduled State?
The same flow runs on other agents, and we are sure the labels are correct because the right Prefect docker agent picks it up to deploy the flow on the VM.
Saw there was an article for submitted state, but it did not help. We are able to pull the image to the machine. The agent process is running and says that it was able to deploy the flow
Solved: Reran with the --show-flow-logs flag. There was a fatal error on executing the flow that was not handled by Prefect.
We used sys.exit(XXXX) in our code instead of raising an error and the process exited without sending anything back to Prefect
@Anna_Geller: Yes, there is! 
Why is my flow stuck in a Submitted State?
Nice work figuring that out! And thanks for using Discourse to find answers to your questions!
