I have deployed Flask app successfully but I am getting application error when I click on the herokuapp link. When I checked logs it shows something like this

I have also used heroku ps:scale web=1
My Procfile includes:
web: waitress-serve --call flaskr:create_app
You must provide the port to bind to (you cannot use the default 8080)
web: waitress-serve --port=$PORT --call 'flaskr:create_app'
