Hi, maybe someone knows why it does not work for me. I'm trying to run simple flow (one flow with print) locally in manually built docker container and I get:

root@3b776c4684ea:/prefect/jobs# python3 simple.py
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/asgi_lifespan/_concurrency/asyncio.py", line 17, in wait
    await self._event.wait()
  File "/usr/local/lib/python3.10/asyncio/locks.py", line 214, in wait
    await fut
asyncio.exceptions.CancelledError

During handling of the above exception, another exception occurred:

This looks like it’s related to the Python script you actually ran right?

yes,

python3 simple.py

:

from prefect import flow

@flow()
def myflow():
    print(["AAAA"] * 15)

    
if __name__ == "__main__":
    myflow()

That’s pretty weird. Can you try with the prefect container instead?

sure, but probably tomorrow ... where can I get the image or dockerfile ?

https://hub.docker.com/r/prefecthq/prefect Maybe like

docker run prefecthq/prefect:2.0b5-python3.8

similar problems using this image (I have copied my simple.py into container and run it with python3:

root@1668c7681eb0:/opt/prefect# python3 simple.py
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/asgi_lifespan/_concurrency/asyncio.py", line 44, in run_and_fail_after
    await asyncio.wait_for(coroutine(), timeout=seconds)
  File "/usr/local/lib/python3.8/asyncio/tasks.py", line 501, in wait_for
    raise exceptions.TimeoutError()
asyncio.exceptions.TimeoutError

so probably something wrong with my docker/ environment ?
