When I try to deploy to Heroku using git push heroku master I get this error: ! [remote rejected] master -> master (pre-receive hook declined) error: failed to push some refs to 'https://git.heroku.com/afternoon-inlet-19669.git'
I found this other StackOverflow question, and it helped me get rid of one of my first errors. Apparently GitHub doesn't update case-changes in file names on commit. So, I realized that I had a file named spinner.js which was actually named Spinner.js on my local machine.
But now, I am getting the error again.

! Push rejected, failed to compile Node.js app.
! Push failed
This is a link to my project on GitHub, any idea why Heroku is refusing to push the app? My Project Link
I believe the solution would be to get Github to realize that my file names have changed, it must still think the file is named spinner.js.
UPDATE: 01/22/2021
You can clear the build cache for an app using the following commands:
$ heroku plugins:install heroku-builds
$ heroku builds:cache:purge -a appname
The cache will be rebuilt on the next deploy. If you do not have any new code to deploy, you can push an empty commit.
$ git commit --allow-empty -m "Purge cache"
$ git push heroku master
Where appname is replaced by the name of the app you want to clear the cache for.
OLD ANSWER for previous versions
You should clean your Heroku cache:
heroku repo:purge_cache -a your_app_name
then try again.
