In DestroyAPIView throw a Error while serializer is None

[shahriar350]

DestroyModelMixin donot required serializer, then why DestroyAPIView throw a error

"
Error [RestoreProductInfoView]: 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: 'NoneType' object is not callable)
"

"
 Error [RemoveImageFromProductView]: 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: 'RemoveImageFromProductView' should either include a `serializer_class` attribute, or override the `get_serializer_class()` method.)
"

my views is:

class RestoreProductInfoView(DestroyAPIView):
    permission_classes = [IsMerchant]

    def get_serializer_class(self, *args, **kwargs):
        return None

    def get_object(self):
        return Product.objects.get(slug=self.kwargs.get('product_slug'))

    def perform_destroy(self, instance):
        instance.deleted_at = None
        instance.save()

why i need serializer while DestroyAPIView response only status.
how to use DestroyAPIView without serializer.

It doesn't seem to be a problem related to DRF.

I was able to find the error in the drf-spectacular library
and the issue docs below may be helpful.

tfranzel/drf-spectacular#308

thank you so much. I thought, that could be a warning from drf.
