SSH Git Transport has reached End of Life
Change effective on 01 December 2021
As Heroku continues to make architecture upgrades to improve performance, the SSH Git Transport feature is deprecated as of November 30, 2021.
The only Git transport configured by the Heroku CLI is HTTP. You must make all git pushes using the HTTP Git deployment method starting December 1, 2021.
To migrate over to the HTTP method, reconfigure your
git:remote with this CLI command:
$ heroku git:remote -a <app-name> and deploy your app using the commands described in the Dev Center. There’s no difference in functionality between the two different deployment methods of SSH versus HTTP.
