Почему не удается подключить djongo в качестве бекэнда?

Question

[Александр Нестеров]

В настройках сконфигурировал БД:

# settings.py
DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': 'django-db',
    }
}

Установил все необходимые пакеты:

установленные пакеты

asgiref==3.5.0
Django==4.0.2
djongo==1.3.6
pymongo==4.0.1
sqlparse==0.2.4
tzdata==2021.5

При попытке выполнения любого действия (запуск сервера/миграция/etc) выскакивает ошибка:
