Django/Wagtail Rest API URL Filter без ответа

Я использую Wagtail и у меня есть API под названием 127.0.0.1:8000/api/v2/stories. В API я имею следующий ответ JSON

    {
      "count": 81,
      "results": [
        {
          "id": 122,
          "title": "Test Blog",
          "blog_authors": [
            {
              "id": 82,
              "meta": {
                "type": "blog.BlogAuthorsOrderable"
              },
              "author_name": "Test",
              "author_website": null,
              "author_status": false,
         },
         {
          "id": 121,
          "title": "Test Blog 1",
          "blog_authors": [
            {
              "id": 81,
              "meta": {
                "type": "blog.BlogAuthorsOrderable"
              },
              "author_name": "Test",
              "author_website": null,
              "author_status": false,
         },
    }

Основная проблема, с которой я сталкиваюсь, заключается в том, что я хочу отфильтровать по имени автора. Я выполнил этот запрос в URL ?author_name=Test & ?blog_authors__author_name=Test & ?author__name=Test Но ответ был

{
  "message": "query parameter is not an operation or a recognised field: author_name"
}

Я добавил эти поля в known_query_parameters, но ответ был таким же, как api/v2/stories/. Я пробовал DjangoFilterBackend, но каждый раз получал один и тот же ответ. Как я могу фильтровать по author_name & author_status в API?

Вот мой api.py

class ProdPagesAPIViewSet(BaseAPIViewSet):
    renderer_classes = [JSONRenderer]
    pagination_class = CustomPagination
    filter_backends = [FieldsFilter,
        ChildOfFilter,
        AncestorOfFilter,
        DescendantOfFilter,
        OrderingFilter,
        TranslationOfFilter,
        LocaleFilter,
        SearchFilter,]
    known_query_parameters = frozenset(
        [
            "limit",
            "offset",
            "fields",
            "order",
            "search",
            "search_operator",
            # Used by jQuery for cache-busting. See #1671
            "_",
            # Required by BrowsableAPIRenderer
            "format",
            "page","author_name",
        ]
    )
    meta_fields = ["type","seo_title","search_description","first_published_at"]
    body_fields = ["id","type","seo_title","search_description","first_published_at","title"]
    listing_default_fields = ["type","seo_title","search_description","first_published_at","id","title","alternative_title","news_slug","blog_image","video_thumbnail","categories","blog_authors","excerpt","content","content2","tags","story_type"]
    nested_default_fields = []
    def get_queryset(self):
        return super().get_queryset().filter(story_type='Story').order_by('-first_published_at')
    name = "stories"
    model = AddStory

api_router.register_endpoint("stories", ProdPagesAPIViewSet)

вот мой models.py для авторов блогов.

        FieldPanel("author"),

    @property

        ),
    
    ]
api_fields = [
        APIField("blog_authors"),
