Question

Hey everyone Trying to figure something out in Prefect 1 is there a way to restart flow runs from the API I am able to cancel flows via the API using the `cancel flow run` function but I don t see a way to restart the run once cancelled

Anna Geller · Answer

there is in theory but it would be very complicated it s easier to create a full new flow run

Anna Geller · Answer

alternatively using retries instead can make things easier to manage

Got it so then is there a way to clone an existing flow run in the create command

Anna Geller · Answer

what do you mean by clone

Krishnan Chandra · Answer

In this case retries won t help me because the run has already finished

Krishnan Chandra · Answer

Basically I have a set of flow runs that got stuck and are now cancelled I want to restart recreate those specific runs

Anna Geller · Answer

I can t find the PR in the UI repo this is the closes I could find <https github com PrefectHQ ui pull 285> but restart is super expensive and complicated operation and UI does a lot of magic here by executing multiple API calls in order to make that happen and it only works if you have results configured on all tasks

Anna Geller · Answer

I d recommend commenting out the tasks that already completed shouldn t be rerun and manually triggering such run if the UI feature doesn t satisfy your use case would that work for you

Anna Geller · Answer

alternatively you can try doing sth similar to this proposal <https github com PrefectHQ prefect issues 5516>
