Pagination classes issue

I spent quite a lot of time to figure out why this library didn't work for me, here are my settings:

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticated',
    ],

    'DEFAULT_AUTHENTICATION_CLASSES': [
        'user.authentication.CustomAuthentication',
        'rest_framework.authentication.SessionAuthentication'
    ],

    # Pagination
    'DEFAULT_PAGINATION_CLASS': 'common.pagination.CustomPagination',
    'PAGE_SIZE': 100,

    # For swagger
    'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema',

    # For excel
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.JSONRenderer',
        'rest_framework.renderers.BrowsableAPIRenderer',
        'drf_excel.renderers.XLSXRenderer',
    ),
}

In the end, I found out that everything didn’t work specifically because I had custom pagination in the drf settings. To fix everything, I needed to add: pagination_class = None. It would be convenient for new users to indicate in the documentation:

from rest_framework.viewsets import ReadOnlyModelViewSet
from drf_excel.mixins import XLSXFileMixin
from drf_excel.renderers import XLSXRenderer

from .models import MyExampleModel
from .serializers import MyExampleSerializer

class MyExampleViewSet(XLSXFileMixin, ReadOnlyModelViewSet):
    queryset = MyExampleModel.objects.all()
    serializer_class = MyExampleSerializer
    renderer_classes = (XLSXRenderer,)
    filename = 'my_export.xlsx'
    pagination_class = None  # If you have a custom pagination class set in your settings
