Second Node App Deploy on Heroku always Fails

Question

Im experiencing a weird issue with Heroku when deploying.

My second deploy (after committing new github changes and pushing them to my app) always seems to crash with the same error message, however, if I create a new Heroku app and deploy it there, it will always deploy successfully.

This is the error that I receive when the build fails.

Im a bit stuck here on what to do. Any help would be great.

To anyone interested, I fixed this by disabling the Node Modules Cache via the Heroku CLI:

heroku config:set NODE_MODULES_CACHE=false --app app_name

This has fixed the build issue.
