I am on the heroku documentation. I am pushing my node app to heroku and it was working fine but I need to change the website name. https://devcenter.heroku.com/articles/renaming-apps
It shows me that I can rename my app very simply
heroku apps:rename newname
Step 2: I just change it on git and I was good to go on the heroku site.
git remote rm heroku
heroku git:remote -a newname
I did the next steps for git and received
! `git:` is not a heroku command.
a app not found when I tried to push to the the heroku master. Is there another step that I am missing?
