Autoprefixer is installed globally somehere and still not found. Hugo gitlab pipeline broken

Using a previously working gitlab pipeline gitlab-ci.yml file suddenly hugo can no longer build and it inexplicably can’t find software it clearly just installed globally. Incidentally folks like to say you don’t need to install autoprefixer globally but here it is required.
This project builds locally no problem.
I have already deleted package.json and pasted in the one for docsy 0.7.1, because this seemed like something similar that fixed this the last time I needed to try and fix this pipeline breakage all of a week ago. Now I am suspicious that the packag-lock.json file is also breaking this. Or there is some broken package thing going on with already deleted and perhaps recreated nodue_modules folder.
Also would like to know how the node_modules and package.json thing can be determined and corrected. 77 Packages seems like a lot for a project where I basically just need postcss, postcss-cli and autoprefixer.

This seemingly functional .gitlab-ci.yml file doesn’t work. Additionally, I would like to know what standard troubleshooting steps can be added to this .gitlab-ci.yml file to identify the breakage and fix it.

autoprefixer IS installed globally however the path needed to find it must be added to the gitlab pipeline thusly:

export NODE_PATH=$NODE_PATH:`npm root -g`

Installing things does not path things.
