应用程序在本地工作，在Heroku上运行 - Node.JS

Question

I'm running a simple express app, it is pulling static files from S3, and runs fine locally, but on Heroku it crashes constantly on a warning about permission denied but with no further info.

Is there a way I could find out what is causing the permission error?

Heroku log from deploy to crash:

您是否将服务器端口绑定到Heroku注入的环境变量$PORT ？
