Django не может разрешить URL-адрес 404

Привет, у меня очень неприятная проблема с django: Я настроил много URL-адресов, и все они работают нормально, кроме одного, и я действительно не могу понять, почему:

URL-адреса

urlpatterns = [
    # path('foods/search', food_search),
    path('food_list/',
         FoodListVersionListCreateAPIView.as_view(),
         name='foodList-list'),
    path('all_foods/<str:survey>/<str:string>',
         FoodListCreateAPIView.as_view(),
         name='food-list'),
    path('food_classification/',
         FoodClassificationListCreateAPIView.as_view(),
         name='foodClassification-list'),
    path('food/<str:survey>/<str:string>/',
         FoodDetailAPIView.as_view(),
         name='food-detail'),
]

    search_fields = ['food_list', 'SYSTEM_TIME']
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]

    def get_queryset(self):
        assert self.queryset is not None, (
            "'%s' should either include a `queryset` attribute, "
            "or override the `get_queryset()` method."
            % self.__class__.__name__
        )

        survey = self.request.query_params['survey']
        food = self.request.query_params['string']
        raw_queryset = perform_food_search(survey, food)
        queryset = Food.objects.filter(pk__in=[i.pk for i in raw_queryset])

        if isinstance(queryset, QuerySet):
            # Ensure queryset is re-evaluated on each request.
            queryset = queryset.all()
        return queryset
