Error when running in poetry environment

[yet-another-account]

When running an experiment in poetry, the following occurs:

Traceback (most recent call last):

Any updates on this? I'm still having issues with this. I think it is happening because the source module is just a normal Python file instead of an installed package, and for some reason its __file__ attribute is None.

I've never had this issue, and I'm not in a poetry environment. Can you further track down the issue? It looks like a module doesn't have a __file__ attribute. I think that this shouldn't happen as long as it is not an interactive python environment.

We could simply check for __file__ being None, but it is not clear what the source file should be set to in that case. Is it even reproducible then?

A quick fix would be to deactivate source gathering by setting SETTINGS.DISCOVER_SOURCES = 'none'.
