Anyone see this error before? I am seeing this in the UI logs after the flow run completes successfully. How to resolve?

An error occurred while monitoring flow run '939028cd-0595-4b3c-bf4a-3c9b123d1e60'. The flow run will not be marked as failed, but an issue may have occurred.

Hi @Moe, I believe this may resolve your issue. Want to give that a try? https://github.com/PrefectHQ/prefect/issues/6446#issuecomment-1219553576

@Serina Hi, thanks. I just changed the way I imported my subflows and no longer experience this issue. Not sure why though but before I had:

import subflow1

def main_flow():
     subflow1.subflow1()

Changing it to this fixed it.

from subflow1 import subflow1

def main_flow():
     subflow1()

Got it, thanks for sharing your before and after! 🙌
