Question

部署后，我在App Engine中收到以下错误。有人知道原因吗？它有时会导致错误页面。似乎simplejson是原因...

根据http://code.google.com/status/appengine/，每个人都应该相应地工作。

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.

这是页面显示的错误：

Error: Server Error
The server encountered an error and could not complete your request.

If the problem persists, please report your problem and mention this error message and the query that caused it.

这似乎不是导致500错误的唯一错误。因为大多数情况下这似乎是原因：

Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team.

Answer 1

这是你的问题：

<class 'google.appengine.runtime.DeadlineExceededError'>

您的页面太慢，应该在30秒内加载。否则，App Engine会将其终止。

Answer 2

似乎真正的问题是文件中有一个“”作为一些注释，这会产生500错误。应用程序现在正在顺利运行。我很高兴我终于找到了它。

因此，如果您收到此错误，请先检查您是否以错误的方式发表评论！
