remote rejected master -> master (pre-receive hook declined)

Question

I\'m working in rails 3.2 and I receive an error when I try to push to heroku:

 git push heroku master
Counting objects: 496, done.
Delta compression using u         


        

Answer 1

For completeness, the issue may be heroku itself. In rare cases like these https://status.heroku.com would show something along the lines of:

Update

The Heroku Dashboard and Elements have been restored. We are still working to restore the other affected services.

The services still affected are:

• Builds
• Review apps
• Pipelines
• Github deploys
• Heroku CI
• Heroku Buttons

I was able to deploy about 40 minutes later after heroku reported:

All affected services have been restored and are now working as expected. We will be monitoring to ensure there are no further issues.
