This is my first attempt at building a full stack application, please help:(. This is my github repo. I'm following this tutorial, but I get a 503 error appearing in the chrome developer tools console when I'm trying to SELECT * FROM todo. I can read the information in my database table through heroku cli & dataclips but it does not work in the heroku app. This is the link to my heroku app, I think the problem is in db.js or index.js but I don't know how to diagnose the problem.

This appears in my heroku cli:
