Развертывание приложения Django в Heroku

Я новичок в Python/кодировании/веб-разработке и сталкиваюсь с ошибками в процессе развертывания.

Я написал приложение для поиска партнеров, используя Python/Django. Я пытаюсь развернуть это приложение с помощью Heroku. Я следовал всем указаниям по настройке сервера, инициализации репозитория Git, созданию профиля, Gunicorn и т. д. и т. д. и т. д.

Я смог git push heroku master.

Однако, когда я действительно пытаюсь синхронизировать свои файлы с базой данных, он возвращает ошибку. Я набрал это: heroku run python manage.py make migrations.

Я получаю следующую ошибку:

Running python manage.py migrate on ⬢ blooming-island-78995... up, run.1306

Что значит auth_user не существует? Означает ли это, что мне нужно создать суперпользователя? Я пытался, и это не позволит мне. Когда я делаю heroku run python manage.py createsuperuser, это дает мне точно такую ​​​​же ошибку.

Вот мой файл models.py для публикации

Кроме того, не уверен, что это поможет, но я выполнил поиск clean_username и основываясь на своих показаниях из этого Пользовательская модель Django в админке, отношение auth_user не существует
