Heroku app successfully deploying, but receiving application error when loading site

My logs don't indicate any errors as far as I can tell, but I'm receiving the following error when loading the site:

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail

Below you can find the logs. Am I missing something here?

Try Manual Deployment again and the error will resolve. Actually it's a temporary solution as this error will again arise after sometime.

Make sure that you have added const port = Process.env.PORT || 3000 ; in your app and remove the localhost if you have mentioned while listening at the port .

server.listen(port,()=>{  // do not add localhost here if you are deploying it
    console.log("server listening to port "+port);
});

Try renaming procfile to Procfile as the message in the logs suggests.
