雲端點-請求失敗的HTTP狀態500

Question

成功部署后，我嘗試致電[xxxxx.appspot.com/_ah/api/*]，但收到錯誤的請求錯誤：500，該方法一直工作到3周前，現在我正瘋狂地嘗試查找原因。 我的自定義API在Google Apis Explorer上也不可見（我也清除了cookie！）。

這似乎是一個實際問題，有相關問題，但任何解決方案都對我有效。

以下是日志：

那里有英雄嗎？ 謝謝！。

提示信息就是該日志消息：“因為實例無法成功啟動，所以請求失敗”。

通常，這意味着您的應用在啟動過程中會引發異常，甚至無法處理請求。 正如saiyr所建議的那樣，您需要查看應用程序日志以獲得解釋。
