500 App Engine(Google Cloud)中我的Django应用程序出现服务器错误

问题描述

我是Google Cloud新手,按照https://cloud.google.com/python/django/appengine中的步骤成功部署了App。但是,当我转到页面https://PROJECT_ID.REGION_ID.r.appspot.com时,显示下一条消息:

错误:服务器错误 服务器遇到错误,无法完成您的请求。 请在30秒后重试。

我看到这真的很常见,但找不到任何有用的解决方案。如有任何帮助,我将不胜感激。

解决方案

您的代码中有错误。500服务器错误表示您的应用程序中有错误。
