Node.js Question

Hroku issue on Deploying Node.js project - simple one

I have recently deployed simple node.js work which does web chatting, really simple piece of codes. But when I visited the URL deployed, it is said following:


Application Error 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.


I have checked the log which is saying:

Any help will be appreciated.

Answer

Well, have you set correct port when to listen? When to deploy to Heroku, you must use following port:

process.env.PORT || {your-config-port}
