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:

• Ubuntu (ubuntu-latest)
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
pnpm ("packageManager": "[email protected]" in package.json at the root of my monorepo)

Repro steps:
This is my GitHub action.

        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          HOME: ${{ github.workspace }}

Expected behavior:
Not really sure what is actually supposed to happen here.

Actual behavior:
With debugging enabled, this is the full trace for the step:
