Hi all - we are working on implementing a solution to send a Slack notification on flow failures with prefect 2.0. It seems like one way to do this is to capture the flow state via the following:

@flow(name="always-fail")
def entrypoint():
    raise ValueError("my error message")

if __name__ == "__main__":
    state = entrypoint(return_state=True)
    print(state)
    print(state.result)

In this scenario,

state.result

can give us the detailed error message for passing back into Slack which seems really useful. However, it’d also be great if we can also provide a direct link to the flow using the flow’s run id. How are other folks implementing this, and is there a way to directly access the flow’s run id after calling the flow from main (or otherwise)?

The flow run id is available at

state.state_details.flow_run_id

Perfect, thank you Michael!

A separate issue seems reasonable, just link to that one and explain how it’s different

Will do, thanks again.
