figure out the source of the error

[bahmutov]

saving NPM modules
saving npm cache failed with Error: Path Validation Error: Path(s) specified in the action for caching do(es) not exist, hence no cache is being saved., continuing...

Fixed in v1.9.0

I'm still seeing this error when using your action. I use a very simple setup:

    unit-test:
        runs-on: ubuntu-latest
        steps:
            - name: Checkout
              uses: actions/checkout@v4
            - uses: bahmutov/npm-install@v1.9.0
            - name: Unit Tests
              run: make test-unit
              env:
                  CI: true

And I get the same error:

saving npm cache failed with Error: Path Validation Error: Path(s) specified in the action for caching do(es) not exist, hence no cache is being saved., continuing...

Is there something special to do to get the cache working with yarn on ubuntu?
