sh: 1: nest: Permission denied in GitHub Action - continuous-integration

Question

For some reason the build step for my NestJS project in my GitHub Action fails for a few days now. I use Turborepo with pnpm in a monorepo and try to run the build with turbo run build. This works flawlessly on my local machine, but somehow in GitHub it fails with sh: 1: nest: Permission denied. ELIFECYCLE  Command failed with exit code 126. I'm not sure how this is possible, since I couldn't find any meaningful change I made to the code in the meantime. It just stopped working unexpectedly. I actually think it is an issue with GH Actions, since it actually works in my local Docker build as well.
Has anyone else encountered this issue with NestJS in GH Actions?
This is my action yml:

I found out what was causing the problem. I was using node-linker = hoisted to mitigate some issues the pnpm way of linking modules was causing with my jest tests. Removing this from my project suddenly made the action work again.
I still don't know why this only broke the build recently, since I've had this option activated for some time now.
