服务器错误（500）访问/admin/with DEBUG=False，前端反应，后端Django（Django rest框架）-Heroku

我有一个应用程序，在前端和后端使用Django rest框架使用ReactJs

该应用程序在Debug=True时工作正常，但当我部署并设置Debug=False时，我可以看到该应用程序工作正常，但是我无法访问管理面板，因为我收到服务器错误（500）。同样奇怪的是，应用程序正确地从API获取数据，但如果我尝试直接访问API，我也会得到服务器错误（500）

我正在使用WhiteNoise处理静态文件，下面是我的代码。在部署之前，我尝试了不同的选择。。在本地执行npm run build和collectstatic（在Heroku中禁用\u collectstatic=1），我还尝试将“postinstall”：“npm run build”添加到package.json文件中，在Heroku中禁用\u collectstatic=0

有人知道我的代码有什么问题吗？见下面我的代码
