Errors & warnings on opening Swagger UI

[koeaw]

The Swagger UI page/API view (.../apis/swagger/schema/swagger-ui/) prints a number of errors and warnings to the console.

I'm copy/pasteing them here for reference (without further analysis):

/PATH/TO/DIR/apis-instance-frischmuth/apis_core/generic/api_views.py: Error [ModelViewSet]: exception raised while getting serializer. Hint: Is get_serializer_class() returning None or is get_queryset() not working without a request? Ignoring the view for now. (Exception: 'ModelViewSet' object has no attribute 'model')

Can you check if this is resolved with the latest apis-core? The old API was removed, so those warnings should be gone

[koeaw]

Some are gone, but some remain, and I'm getting new ones now, too.

Split up for readability:

apis_core/core:

/PATH/TO/DIR/apis-instance-frischmuth/apis_core/core/views.py: Error [Dumpdata]: unable to guess serializer. This is graceful fallback handling for APIViews. Consider using GenericAPIView as view base class, if view is under your control. Either way you may want to add a serializer_class (or method). Ignoring view for now.

apis_core/apis_entities:

/PATH/TO/DIR/apis-instance-frischmuth/apis_core/apis_entities/api_views.py: Error [GetEntityGeneric]: unable to guess serializer. This is graceful fallback handling for APIViews.

New warnings which originate from django_filters/filterset.py:

For classes in APIS Core:

For entity classes in my models – looks like there is one (identical one) per model class:

Tested with local copy of APIS Core on latest main branch, on latest Frischmuth deploy branch.

[koeaw]

But I guess it's possible those latter errors are unrelated and due to something that changed in Frischmuth between then and now. (?!)
