Hello everyone! Does sb know if there is a on_cancelled hook that we can use for flows to execute code on cancellation (e.g like cleanup of things)?

There doesn't seem to be an

on_cancelled

hook, but you should be able to access the run state as described in this example: https://discourse.prefect.io/t/how-to-take-action-on-a-state-change-of-a-task-run-task-level-state-handler/82 It seems that this only applis to tasks though, not flows. Perhaps it might work if you submit your flow as a subflow and access the future from the parent flow.

Note

on_cancelled

si coming soon? 😄 i think i remember reading it somewhere

@Deceivious Probably thinking of https://github.com/PrefectHQ/prefect/pull/9389 🙂

The

on_cancellation

flow run state change hook is released. Please see our new documentation for more details: https://docs.prefect.io/latest/concepts/states/#state-change-hooks
