Failure to restore cache `Cannot mkdir: Permission denied`

See original GitHub issue

Description: This seems like another instance of https://github.com/actions/setup-node/issues/362, but it’s happening with github-hosted runners, and using yarn instead of npm, and actions/setup-node@v3 instead of v2.

At some point, the cache seems to have been corrupted, and now it fails on multiple PRs.

The java setup action also seems to have a similar issue https://github.com/actions/setup-node/issues/459 but I can’t guess if it’s related.

Action version: actions/setup-node@v3

Platform:

Ubuntu
macOS
Windows

Runner type:

Hosted
Self-hosted

Tools version: node v12.22.12 yarn v1.22.17

Repro steps:

This is happening in a private repo, whenever the action runs. It might have started happening after I tried to bump the ancient node version used there in a specific PR, but affecting unrelated ones.

The job is straightforward

  unit_tests:
    name: 'Unit tests'
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Setup node
        uses: actions/setup-node@v3
        with:
          node-version: '${{ env.NODE_VERSION }}'
          cache: 'yarn'
      - uses: webfactory/ssh-agent@v0.5.0
        with:
          ssh-private-key: ${{ my-key }}
      - name: Install dependencies
        run: yarn install --ignore-optional --frozen-lockfile --non-interactive
      - run: |
          yarn test:ci

Expected behavior:

Cache is either restored or the job works as if there was a cache miss

Actual behavior: The job fails. Notice cache size is super tiny, which seems an indication that something else went wrong, but an invalid value is being propagated.
