Prefect Community

Hi Team, I see an issue in my Prefect server (0.13.10) environment. When the flow is removed during execution, there are a lot of errors reported and it will not stop. Is this an known issue?
`prefect.utilities.exceptions.ClientError: Flow run ID not found: "3b51f006-cbbe-459c-b74f-6a832f22db96"`

Errors are like this:
```Traceback (most recent call last):

File "/usr/local/lib/python3.9/site-packages/prefect/engine/cloud/flow_runner.py", line 179, in interrupt_if_cancelling

flow_run_info = self.client.get_flow_run_info(flow_run_id)

Why is the flow getting removed here? I think this would be expected if you’re deleting a flow mid run because you’re removing it from the database, but the flow is updating states of tasks in the database using the flow run ID. Does that make sense?

Thanks <@U01QEJ9PP53>, it’s fine to report the error and stop. But my concern is the agent keeps reporting the error like in a dead loop.

I replicated this on KubernetesRun by checking the logs of my pod, but could not replicate in with LocalRun. Just checking if you’re using Kubernetes?

Thanks <@U01QEJ9PP53>, yes I run it in Kubernetes

The issue is <https://github.com/PrefectHQ/prefect/issues/4952|here>

Thanks <@U01QEJ9PP53>! is there a plan to get it fixed?

I can’t give a timeline on this honestly as I have no idea how involved the fix is. ~I may have an answer for you on tuesday.~ Let’s see if the core team chimes in on that issue in a bit.
