[FIXED] Why is Heroku site not working with my app name? [Application Error]

Issue

I have pushed files from my computer to heroku using git which bundles the app to publish on the web during a Udacity course.

When I use https://git.heroku.com/mmishal001.git as per my git bash output - it gives me Method not allowed

On doing research there was a stack answer to use https://mmishal001.herokuapp.com/ but its giving me an Application Error

How can I successfully view my site?

Here are the logs:

This is the port info from the .py file,

Solution

Heroku automatically assigns your heroku app a port, so when you can't set the port to a fixed number. Heroku adds the port to the env, so you can pull it from there. Switch your listen to this:

.listen(process.env.PORT || 5000)

That way it'll still listen to port 5000 when you test locally, but it will also work on Heroku.
