Невозможно добавить пользователя через страницу администрирования django

Question

Я использую страницу django-admin, чтобы добавить пользователя в свое приложение. Недавно, когда я попытался добавить нового пользователя, я начал получать TypeError.

Точная ошибка: -

Тип исключения: TypeError at / admin / auth / user / add / Exception Значение: объект 'float' недопустим. Информация запроса

Поскольку я ничего не изменил в коде, я не уверен, почему я получаю эту ошибку сейчас. Вот почему я в растерянности, что попытаться решить проблему.

Я прилагаю трассировку здесь: -

Было бы очень полезно, если бы кто-то указал мне правильное направление.
