How do I uninstall this buildpack in Heroku?

Question

I installed heroku-buildpack-php-tyler on my Heroku app a few days ago, and it all seemed to work fine. I installed it by running the following command:

heroku config:set BUILDPACK_URL=git://github.com/iphoting/heroku-buildpack-php-tyler.git

However I now want to remove it. I tried using the following command:

heroku config:unset BUILDPACK_URL=git://github.com/iphoting/heroku-buildpack-php-tyler.git

But it returns the following error message:

Unsetting BUILDPACK_URL=git://github.com/iphoting/heroku-buildpack-php-tyler.git and restarting hnf-heroku... failed

! Resource not found`

Because PHP isn't officially supported by Heroku, there's not much documentation about this. So how do I uninstall this buildpack?

Try:

heroku config:unset BUILDPACK_URL
