If you get this error and the terminal is not descriptive enough to help you, Heroku might be able to tell you what is wrong through their website. Try the following:

log in to Heroku and go to your dashboard;
select the problem application from the list; and,
check the build logs under the "Activity" tab.

In my case, I had accidentally ignored my Gemfile.lock.

Specify the version of node The version of Node js that will be used to run your application on Heroku  should also be defined in your package json file  You should always specify a Node js version that matches the runtime you   re developing and testing with  To find your version type node --version   Your package json file will look something like this    engines          node    10 x        It should work

Make sure that your Rails app is in the root of the repo  the Gemfile is present and properly named  It is basically not able to detect your code base as one of the supported project types and hence failing it  Also  even if you do have a proper project  make sure it is part of the repository and you have committed it fine  git status will help you here and a ls should help you verify the project structure

In Heroku  you may have problems with pushing to the master branch  What you can do is to start a new branch using     git checkout -b tempbranch   and then push using     git push heroku tempbranch

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

If you run   heroku logs you may get a  hint  to what the problem is  For me  Heroku could not detect what type of app I was creating  It required me to set the buildpack  Since I was creating a Node js app  I just had to run   heroku buildpacks set https   github com heroku heroku-buildpack-nodejs  You can read more about it here  https   devcenter heroku com articles buildpacks  No pushing issues after that   I know this is an old question  but still posting this here incase someone else gets stuck

I also faced the same issue The solution for this is Delete the package-lock json file on both the client and server Make sure that you are using at least the LTS version of Node locally Make sure your local Node version matches what is shown in the package json file s engines property  Run the git add     git commit -m  quot fixing versions quot  and git push heroku master commands to force a rebuild

You might also want to check for Heroku telling you there s a typo in your CSS file    Read through the long boring messages in the terminal closely after you push  There may be something like this  Invalid CSS after  It means Heroku has found a typo and you need to fix it in the CSS file   You can do a find for rake aborted  and directly after that it should say why the push failed
