I've successfully deployed my Django app with Fly.io.
But ever since I followed William Vincent's 'Django for Professionals' by trying to Dockerise my project, I have had no luck with updating my production server. In fact, I cannot deploy at all anymore.
I ran heroku logs --tail and this is what I got.
May you please offer any explanation as to why my 'release command' is failing?
heroku logs --tail

If you need to see any of my files, please advise which ones. I've only taken 2 apps into production but never through Docker.
Thank you
