Hello @wenkokke. Thank you for your report. I've tried to reproduce the issue with pure yml file but it works as expected. Npm and npx are available.

    steps:
    - name: Checkout repository
      uses: actions/checkout@v3
    - name: Setup Node
      uses: actions/setup-node@v3
      with:
        node-version: 16
    - run: |
        npm --version
        npx --version

Hello @wenkokke. For now I'm going to close the issue because npm and npx are installed and added to PATH. If you have any additional information feel free to ping us.

I'm having this issue. Here's the failed build:
