cache-dependency-path with npm to a subfolder does not work

Description: cache-dependency-path to a subfolder results in Error: Some specified paths were not resolved, unable to cache dependencies.

Action version:

actions/setup-node@v3

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

The node 16.x version with corresponding npm version you get in Github.

node-version: 16 check-latest: true

Repro steps:

Relevant workflow part:

jobs:
  # This workflow contains a single job called "build"
  build:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      - name: setup node
        uses: actions/setup-node@v3
        with:
          node-version: 16
          check-latest: true
          cache: "npm"
          cache-dependency-path: "${ GITHUB_WORKSPACE }/functions/package-lock.json"

But for cache-dependency-path I’ve also tried these strings:

• “functions/package-lock.json”
• “./functions/package-lock.json”
• “*/package-lock.json”

And they all fail:

Environment details
/opt/hostedtoolcache/node/16.18.0/x64/bin/npm config get cache
/home/runner/.npm
Error: Some specified paths were not resolved, unable to cache dependencies.

Expected behavior:

Caching to work even though the package lock file is in a subfolder called functions.

Actual behavior:

See repro steps above.
