Hey All, I’m having an issue with a flow that is registered with the Hybrid model approach where I have a docker image and the flow with a DockerConfig to run it from the cloud. This was working in a the past but as of a few days ago, flow run gets triggered but no run is being performed. This leaves the run in Submitted state with a few attempts to re-run and Lazarus service finally kills it. I have other flows registered/installed and working within the same environment so I a little puzzled as to why this flow does not run. Any debugging suggestion would be appreciated.

That is very weird. Especially if other Docker flows are running. I would suggest enabling DEBUG level logs on the agent with

prefect agent docker start --log-level=DEBUG

and maybe we can get some insight why the Flow is not starting

Good starting point. Do you think it had anything to do with the Docker Agent and the Flow environment being on different version of Prefect?

Potentially. Agent version needs to be at least as high as the Flow version
