Test_add_movie_invalid_json fail Курс: Тестируемая разработка с Django, Django REST Framework и Docker

В курсе Test-Driven Development with Django, Django REST Framework, and Docker я добавил модульные тесты в раздел Restful Routes. но когда я запускаю pytest, новый тест не работает.

Я не уверен, почему этот тест не работает.

@pytest.mark.django_db
def test_add_movie_invalid_json(client):
    movies = Movie.objects.all()
    assert len(movies) == 0

    resp = client.post(
        "/api/movies/",
        {},
        content_type="application/json"
    )
    assert resp.status_code == 400

    movies = Movie.objects.all()
    assert len(movies) == 0
