I have a simple Flask app that I'm trying to deploy to Heroku, but I'm facing an Application Error and the logs seem to indicate that the app is stuck in some sort of restarting loop. I think there is a problem with my Procfile or run.py but I can't figure out what. Here are the Heroku logs:

web: gunicorn run:app
#!flask/bin/python
from app import app
app.run(debug = True)
from flask import Flask
app = Flask(__name__)
from app import views
From there views.py runs and is pretty classic. I've seen a few similar questions and tried playing with my Procfile but couldn't get it work, all I managed to do was crashing the app. Any suggestions?
The problem is that your run.py
runs your application when gunicorn imports it. You only want that to happen when you execute it.
#!flask/bin/python
from app import app
if __name__ == '__main__':
app.run(debug = True)
