`git push heroku master` returns error

Question

I am trying to create a simple project on Heroku by pushing a git which contains only a php ('Hello World') file, am empty README file and an empty json file.

When I enter git push heroku master in the terminal to do this I (partly) get the following response:

remote:  !     Push failed due to an unrecognized error, and we've been notified.
remote: 
remote:  !     Please try pushing again.
remote:  !     If the problem persists, see http://help.heroku.com/ and provide Request ID *my_project_id*.
remote: 
remote: 
remote: Verifying deploy...
remote: 
remote: !   Push rejected to *my_project_name*.
remote: 
To https://git.heroku.com/*my_project_name*.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/*my_project_name*.git'

Because of this I cannot properly run any new Heroku app (which may include only a php 'Hello World' file).

This error was presented suddenly after I have already used successfully git push heroku master for dozens of heroku apps (the same day). Actually, this error was presented to me also when I tried to edit an app which was already running properly.

How can I fix this?

Answer 1

I am pretty sure that I was affected by deployment failures occurring on Heroku itself and it was not anything about what I did which caused this error.

When something goes wrong I tend to think that I am doing something wrong but sometimes it may be that something wrong is occurring at the other side of my computer.
