장고 어드민 로그인 오류

안녕하세요 선생님!

다름이 아니라 제가 db를 sqlite에서 mysql로 변경후 python manage.py runserver 를 통해

admin 사이트 로그인을 한후에 이런 오류가 뜨는데 무엇이 문제인지 잘 모르겠습니다.

다시 db를 sqlite로 바꾼후에는 로그인이 잘 되는것을 확인하였습니다![24/Nov/2022 21:35:22] "POST /admin/login/?next=/admin/ HTTP/1.1" 500 175618

[24/Nov/2022 21:35:23] "GET /admin/login/ HTTP/1.1" 200 2217
