Cache not found for input keys

Not sure what I’m missing here:

jobs:
  tests:
    name: Run all tests
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Setup node 14
        uses: actions/setup-node@v1
        with:
          node-version: 14.x
      - name: Get yarn cache directory path
        id: yarn-cache-dir-path
        run: echo "::set-output name=dir::$(yarn cache dir)"
      - uses: actions/cache@v2
        id: yarn-cache # use this to check for `cache-hit` (`steps.yarn-cache.outputs.cache-hit != 'true'`)yarn cache dir
        with:
          path: ${{ steps.yarn-cache-dir-path.outputs.dir }}
          key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}
          restore-keys: |
            ${{ runner.os }}-yarn-

Oh, most of issuer above is using v2, let me try v3! One of my friends’ new repo that is using v3 is working nicely.

Yes, package-lock file only changes after doing npm i. So, this should be the reason. Closing now. Thank you.
