    have you looked at the logs for your app on heroku? including something from those may help people understand the problem. – Ryan Quinn Mar 15 '20 at 19:47

Without knowing more about the project, my first guess is something that I ran into just yesterday, where Environment Variables hadn't been declared within Heroku > App > Settings > Config Vars, but were properly in place in the dev environment in the .env file (which should never, ever, ever be pushed to any repository, just so you're aware).

If you could run heroku logs --tail in your CLI and paste in the log for that app, it could help clarify exactly what's happening.
