Docker pushing to Heroku "Unexpected HTTP status: 500 internal server error"

docker heroku .net-core dockerfile heroku-cli

Solved:

I forgot Heroku uses Linux containers! I was trying to build and deploy using windows containers still.

Building after switching has resolved this issue :)

docker heroku .net-core dockerfile heroku-cli

I also faced the same error, in my case the registry was full. So I added archival policy to the images and made some space, it solved my problem.
