Problem: I am creating a flow where the task needs to enter state Completed even if it raises an error. The final state of the flow if this task fails should be Completed (and not Failed). I need to raise and error in order to stop all upstream functions from executing.
Here is a dummy code, which I need help with.
import prefect def handle_disambig_error(task_future: prefect.futures.PrefectFuture): task_future.wait() # block until completion if task_future.get_state().is_failed(): # future.result() task_future._final_state = prefect.states.COMPLETED return task_future @prefect.task def fail_successfully(): raise @prefect.flow() def main_flow(): future_obj = fail_successfully().submit() handle_disambig_error(future_obj) if __name__ == "__main__": main_flow()
Again, I cannot remove the raise from the task and return the 0 as then I would have to change multiple upstream functions. I do not want the task to end in failed state as this causes my final flow to fail. I want the flow to fail when other, more crucial tasks fail and not the mentioned one.
Thank you for your help!
