hey all! when I was first setting up our prefect.yaml I included a pull step of our git repo that wasn't actually needed because we copy the files over into the docker container. I'm trying to refactor some code but the flows on my branch are now stuck on

Flow could not be retrieved from deployment.
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/prefect/engine.py", line 422, in retrieve_flow_then_begin_flow_run
    else await load_flow_from_flow_run(flow_run, client=client)

    a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType

I'm trying to backtrack and figure out where I went wrong but does anyone know how to get more info from this statement? is it saying that based on the

entrypoint

I specified for my flow in the prefect.yaml, it's now unable to find that path in the docker container?

Hi Tomas! Hmm..could be something with the entry point or maybe the path to the working directory. What does the pull step of your

prefect.yaml

look like now? 👀

that's the thing, I don't have a pull step in my prefect.yaml. the code already exists and the working dir is set in the dockerfile so that the path in the entrypoint of the prefect.yaml should work. I can put together a dummy prefect.yaml in a sec but is not having a pull step potentially messing up my flow?

Lack of a pull step could be the issue. Whenever I create a custom docker image with my code baked in, I have this pull step in my

prefect.yaml

pull:
- prefect.deployments.steps.set_working_directory:
    directory: /opt/prefect/<WORKING-DIRECTORY>

awesome, let me try adding that. thank you @Bianca Hoch!

give it a go

for sure, I'll work through this and dm you the dockerfile + prefect.yaml if it doesn't work
