我有一个在本地运行良好的django项目，还有一个为django应用程序正确创建Docker映像的Dockerfile。该映像可以在Heroku上很好地部署，并可以正确打开登录到管理页面。如果我输入了错误的凭据，则应用程序会迅速引发无效的凭据错误。但是，如果我输入正确的凭据，则该应用程序将继续运行，直到Heroku超时（无法更改的30秒）到期为止。
我正在使用Postgres插件，并且由于上面提到的凭据错误（当我尝试使用不正确的用户登录时），我认为它的配置正确（以及settings.py）。
请求超时时在日志中引发的错误如下：

您可以看到它完整here
我在Dockerfile上的这一行在Heroku中启动该过程：
CMD [“ sh”，“-c”，“ python3 manage.py runserver 0.0.0.0:$PORT”]
我也尝试过使用gunicorn，但仍然遇到相同的错误。
我想我缺少了什么，但我不知道什么。
