將Sails.js應用程序部署到Google App Engine時超時

Question

我嘗試將一個新的Sails.js應用程序部署到Google App Engine。當我簡單地部署框架（使用CLI sails new web-service創建的vanilla Sails.js應用程序）時，它工作得很好。部署發生得很快，我可以通過訪問該URL來訪問該應用程序。

我配置了ORM /config/connections.js以連接到mLab MongoDB數據庫。這種變化之後，應用程序工作正常，我的本地機器上，但是當我使用的終端部署到谷歌應用程序引擎，我得到以下控制檯錯誤：

Updating service [default]...failed.

這裏是npm-debug.log輸出：

它是否無法啓動，因爲它無法連接到mLab數據庫？如果是，那爲什麼？在我的本地機器上工作得很好。增加超時會有幫助嗎？如果是的話，我該怎麼做？

好吧，我設法通過更改ORM hookTimeout來解決此問題。

在/config/env/development.js和/config/env/production.js，添加以下：

module.exports = { 

    // Extends the ORM timeout to connect to the database 
    hookTimeout: 240000 
};
