For most Node.js apps this buildpack should work just fine.
If, however, you're unable to deploy using this new version of the buildpack, you can get your app working again by locking it to the previous version:
In production, you frequently want to lock all of your dependencies - including
buildpacks - to a specific version. That way, you can regularly update and
test them, upgrading with confidence.
First, find the version you want from [the list of buildpack versions](https://github.com/heroku/heroku-buildpack-nodejs/releases).
Then, specify that version with `buildpacks:set`:
```
heroku buildpack:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-nodejs#v63 -a my-app
git commit -am "empty" --allow-empty
git push heroku master
heroku buildpacks:set https://github.com/heroku/heroku-buildpack-nodejs#v75 -a my-app
```
Then please open a support ticket at [help.heroku.com](https://help.heroku.com/) so we can diagnose and get your app running on the default buildpack.
If you have trouble upgrading to the latest version of the buildpack, please
open a support ticket at [help.heroku.com](https://help.heroku.com/) so we can assist.
