Prettier with WSL not working

I can't seem to get the "Reformat with Prettier" to work. I'm using WSL and can for example get "Fix Eslint Problems" to run just fine. I have connected my NPM/Node to nvm installation on WSL. I have also installed the prettier plugin.

Prettier does however work from Terminal (bash) without any problems (node_modules/.bin/prettier app.js)

What happens when I try reformat is basically... nothing. Occasionally I see the "node interpreter is not correct", but the exact same setup works for eslint...

The prettier package input field correctly displays the package version (I've also tried different paths such as \.bin\prettier).
