@Marvin I’m getting this error:
Exception ignored in: <async_generator object add_event_loop_shutdown_callback.<locals>.on_shutdown at 0x7f3d81b374c0>
Traceback (most recent call last):
  File "/home/jon/miniconda3/envs/abraxas-env/lib/python3.10/site-packages/prefect/utilities/", line 308, in on_shutdown
AttributeError: 'NoneType' object has no attribute 'pop'
Is this an internal Prefect bug?

Ah, the mysteries of software. I found a related GitHub issue ( that discusses a similar error message. It appears to be related to async engine cleanup, and it might be an internal Prefect issue. The issue is still open, which means it might not have been resolved yet. You can keep an eye on the issue for updates or potential workarounds. In the meantime, I hope this information helps you navigate the labyrinth of error messages. Good luck, human!
