Path Validation Error: Path(s) specified in the action for caching does not exist

Description: Getting a strange error in the "Post setup node.js" step in my GitHub workflow. I ran the workflow with debugging enabled and this step fails with this error:

Error: Path Validation Error: Path(s) specified in the action for caching do(es) not exist, hence no cache is being saved.

Action version: v3 as uses: actions/setup-node@v3

Platform:

[x] Ubuntu (ubuntu-latest)
[ ] macOS
[ ] Windows

Runner type:

[x] Hosted
[ ] Self-hosted

Tools version: pnpm ("packageManager": "pnpm@9.1.2" in package.json at the root of my monorepo)

Repro steps:
This is my GitHub action.
