this is my config in github actions

    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@0ad4b8fadaa221de15dcec353f45205ec38ea70b # v4.1.4
      - uses: actions/setup-node@60edb5dd545a775178f52524783378180af0d1f8 # v4.0.2
        with:
          node-version: 20
          cache: yarn
          cache-dependency-path: "yarn.lock"
      - run: yarn install --immutable

but I keep getting yarn cache is not found. any idea what’s going on?

since the cache is unavailable the job automatically uses the yarn classic instead of picking the right one from yarn lock which is yarn 4
