MiddlewareMixin отсутствует необходимый аргумент: 'get_response' django

Есть ли у кого-нибудь идеи, почему я получаю эту ошибку? Моя программа работала раньше, и я не знаю, что я изменил, чтобы вызвать ее поломку.

Мой основной сайт работает, но всякий раз, когда я делаю этот get запрос к http://10.0.0.233:8000/watcher/form/list я получаю ошибку, описанную ниже. Я просмотрел весь свой проект и не нашел нигде использования MiddlewareMixin.

urls.py:

from django.urls import path
from . import views

urlpatterns = [
    path('form/list',views.get_all_form_items),
]

Views.py

@api_view(['GET'])
def get_all_form_items(request):
    snippets = form_item_db.objects.all()
    serializer = form_item_db_serializer(snippets, many=True)
        
    return Response(serializer.data)

Ошибка:
