node.js - Heroku - NodeJS 应用程序错误

Question

我通过 github 部署了该应用程序，一切顺利。但是当我打开网站时出现:

应用程序错误

An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

我知道有一个文件丢失。但它在哪个文件中调用丢失的文件呢？

新错误。这次又发生什么事了？

Answer 1

看起来它从文件“/app/config/config.js”第 9 行抛出错误。
