I have a react app (CRA) hosted on Firebase. I followed a tutorial or documentation several months ago to configure it. I’ve since forgotten all the steps I took and what resources I found.

In June 2024, GitHub deprecated Node v16 and began enforcing Node v20 for all actions.
https://github.blog/changelog/2024-03-07-github-actions-all-actions-will-run-on-node20-instead-of-node16-by-default/

Now when I push to ‘main’ I get this error and warning:
GitHub Action job

I’ve read through that article and all the linked resources. I’ve tried a few edits to firebase-hosting-merge.yml, but I seem to always break the action worse. Any altered form of the yaml file yields just the ‘exit code 1’ error on the GitHub action, without the warning.

name: Deploy to Firebase Hosting on merge
'on':
  push:
    branches:
      - main
jobs:
  build_and_deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: npm ci && npm run build
      - uses: FirebaseExtended/action-hosting-deploy@v0
        with:
          repoToken: '${{ secrets.GITHUB_TOKEN }}'
          firebaseServiceAccount: '${{ secrets.FIREBASE_SERVICE_ACCOUNT_xx }}'
          channelId: live
          projectId: xx

I’ve tried changing actions/checkout@v3 to v4. I’ve tried a few things to specify node20, all without success.

I’m looking for the right way to bring this action current. Is this a simple edit to the yaml, or do I need to run firebase init again? or firebase init hosting:github? Thanks in advance!
