'No module named ...' when referencing external files from flow with DaskTaskRunner

[cvetelinandreevdreamix]

Bug summary

Hi, all,

I'm opening a new issue as it seems my comments on the closed one (#15783 ) are ignored.

I'm attaching a project you can use to reproduce the error
test-prefect-migration copy.zip

2024-12-06 12:06:12 ModuleNotFoundError: No module named 'common'

It happens when:
I deploy the flow to Minio. Use python deployment.py
I use a function from another module in the task I want to run with dask
If I run the flow from the local file system (python deployment.py) then it works fine
If I deploy and flow and I don't use a function imported from another module, then it works fine

My case is that I have a shared code between multiple flows and it is extracted in a shared module (common).

I can see the common folder is deployed to Minio.

P.S
The deployment of the flow to Minio doesn't work if I define the flow with the RemoteFileSystem class:

@flow(task_runner=DaskTaskRunner(), result_storage=RemoteFileSystem.load('minio-results'))

It works if i give just the slug

@flow(task_runner=DaskTaskRunner(), result_storage='remote-file-system/minio-results')

Let me know If you need more information. I need to migrate to prefect 3 and use the automations.

Thank you for your time!
