pnpm error upon fresh install in embroider app

Question

I switched to pnpm in most of the apps that I maintain and it's an amazing tool. What I don't understand is how to troubleshoot dependency issues. I would really appreciate some help.

The problem comes from one ember-specific addon, and I opened a new issue in their repo, but I'd like to be able to figure out what to do in case issues like that happen with dependencies in general.

The error is Cannot find module ..., if you add the missing module there's another "missing" one and another one and another one ...
