Cannot sign/notarize a macOS app

Hi,

I'm trying to use this action to sign and notarize an macOS app (my_app.app).

I use this in my workflow:

// ... build the app
      - uses: actions/upload-artifact@v4
        with:
          path: .release/my_app.app
          if-no-files-found: error
      - name: codesign app
        uses: lando/code-sign-action@v2
        with:
          file: .release/my_app.app
          certificate-data: ${{ secrets.APPLE_CERTIFICATE_DATA }}
          certificate-password: ${{ secrets.APPLE_CERTIFICATE_PASSPHRASE }}
          apple-notary-user: ${{ secrets.APPLE_NOTARIZATION_USERNAME }}
          apple-notary-password: ${{ secrets.APPLE_NOTARIZATION_PASSWORD }}
          apple-team-id: ${{ secrets.APPLE_TEAM_ID }}
          apple-product-id: com.example.my_app
          options: --options runtime

I can see that the actions/upload-artifact uploads my app correctly, but the code-sign-action reports:

/Users/runner/work/my_app/my_app/.release/my_app.app does not exist!

I guess the issue is that the macOS app is just a folder on the file system, and that this line of code only checks for files but not folders:

https://github.com/lando/code-sign-action/blob/a2d97da1cd6f31537bf59de53943c8c1acbb1eac/action.yml#L298

Start at action.yml line 298, which the report identifies as checking whether the .app path exists, and compare its behavior for a macOS app bundle directory. Reproduce the workflow with .release/my_app.app and verify that the action accepts the bundle, then confirm that signing and notarization proceed without the reported missing-path error.
