Heroku上的Express JS应用显示应用程序错误

Question

I am trying to host my Express JS app on Heroku, I have uploaded it on my gitHub repo and associated it with my heroku account. I created the Procfile with content

web: node app.js

But when I go to my application link on Heroku it gives Application Error.

What I am doing wrong? Do I need to give my index.js instead of app.js?

Answer 1

I upgraded my git to 2.3.0 and now the logs are coming in. It seems the issue was that no web dynos were running.

I went in my terminal and did

heroku logs --app myappname

heroku ps:scale web=1 --app myappname

and now the application is working
