error: RPC failed; result=22, HTTP code = 400

Question

I am trying to push my app on to Heroku, but I am getting this error message. I have looked around, someone mentioned about GitHub recently started redirecting http reposito

Answer 1

It could be a glitch, as I mentioned in here.
(Actually, right as I write this, GitHub is having a "Major service outage"!)

Make sure you can reproduce the issue with an http or an https url.
If that persists, simply try and swith to an ssh url

git remote set-url heroku git@heroku.com:yourRepo

(which is the recommended approach, since heroku normally support ssh only)
