Chris White · Answer

yea if you delete all flow runs that were associated with this deployment it should unblock you we should have better error handling for this situation also I can open a PR for that

Is there an easy way to find the flow runs with this deployment

Chris White · Answer

great thank you i believe you can query your DB directly looking at the deployment id on the flow run table i believe we don t enforce a FK on that so it should still be present with the value ```762eab44 76ca 44ee 8334 f2a5d46d4883``` Otherwise I suggest looking at all Cancelling runs associated with your work pool

Chris White · Answer

hopefully i can get this PR into the next release which will solve this problem automatically for you <https github com PrefectHQ prefect pull 9464>

Finding the Cancelling ones and deleting them did it Thank you
