/usr/bin/jq: Permission denied [dokku]

Hi! Thank you so much for this helpful buildpack. Up until very recently (last push maybe a month ago?) I've used it on multiple projects without issue, but I now get this permission / no such file error when deploying via dokku.

I appreciate this is a heroku buldpack and isn't designed for dokku, but if there's a simple workaround for this issue, would be extremely helpful!

It also happened to me using dokku.
It's related to a bug in the heroku-buildpack-nodejs master branch, referenced here
They mention that using a specific version, heroku-buildpack-nodejs#175 the issue is solved.
So maybe this buildpack should point to the latest stable version instead of the master branch

I submitted the PR that fixes the issue, in the meantime I'm referencing it through the fork https://github.com/jpvillaseca/create-react-app-buildpack.git but once it's merged I'll be able to go back and reference this repo directly in my dokku app.
