git – heroku: src refspec master does not match any

Question:

I’m hosting on Heroku. When I push:

git push master Heroku

1 2	git push master Heroku

I get the error:

error: src refspec master does not match any.
error: failed to push some refs to 'git@heroku.com: etc ...'

error: src refspec master does not match any.

error: failed to push some refs to 'git@heroku.com: etc ...'

This is work for me:-

git push heroku HEAD:master

1 2	git push heroku HEAD:master
