Hello! I put together a shopify app for testing purposes using the "shopify_app" gem. The app works great when I run it from localhost, but when I put it up on Heroku the app breaks with a 500 error after attempting to login.
I've changed the callback url from http://localhost:3000/login to https://blueberry-surprise-2198.herokuapp.com/login so that the redirect_uri and application url would match. Is this the callback url I should be using?
Is there any other configuration needed for shopify apps to work on Heroku?
