we had an issue that might not be similar to yours but we were not getting any useful info from the logs with regards to the reason for the app crash.

However if you run heroku run rails console it gave a more specific error, which helped us resolve the issue.

You have not defined port specifically, Heroku is trying to start the project on the different port.

var port = process.env['PORT'] || 3000;

I had used app.set("port" , process.env.PORT || 3000); and in listen app.get("port") , but still commit the change as per your answer sir , still i m getting application error . – Emir Sarrafoglu Aug 31 '18 at 12:50
Change main from index.js to server.js in your package.json file. – sachin Sep 01 '18 at 07:41
In package.json , there is already a script tag consisting node server.js as start object – Emir Sarrafoglu Sep 02 '18 at 10:53
