Background
I'm at the end of my rope. For the last few weeks, I've been on a wild goose chase trying to get my Postgres database on Heroku again. Finally, I ended up scrapping the old one and created a new database from scratch and built everything thing up to where I had it before. This is where I am now.
Error

The the release phase begins, and while no error is displayed, I still exit with a status 1 and the app fails deployment to Heroku:

I solved this problem with edit my procfile, you need to remove release: pipenv run upgrade from your procfile and try again, you can upgrade pipenv using heroku cli and another way you can use virtualenv.Good Luck!
