Ubuntu – GET flutter_bootstrap.js net::ERR_ABORTED 404 (Not Found)

I am trying to deploy a Flutter web app to Firebase hosting using the FirebaseExtended/action-hosting-deploy action and the experimental webframeworks flag. Here is my GitHub workflow file:

name: Deploy to Firebase Hosting on merge
on:
  push:
    branches:
      - main
jobs:
  build_and_deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Set up Flutter
        uses: subosito/flutter-action@v2
        with:
          channel: stable
          flutter-version: 3.19.0
      - uses: FirebaseExtended/action-hosting-deploy@v0
        with:
          repoToken: ${{ secrets.GITHUB_TOKEN }}
          firebaseServiceAccount: ${{ secrets.FIREBASE_SERVICE_ACCOUNT_FLUTTER_FAST }}
          channelId: live
          projectId: flutter-fast
          target: flutter-ast-viewer
        env:
          FIREBASE_CLI_EXPERIMENTS: webframeworks

Whenever this workflow runs, the web page gets updated but it’s blank and the following error appears on the network tab:

GET https://flutter-ast-viewer.web.app/flutter_bootstrap.js net::ERR_ABORTED 404 (Not Found)

If I deploy the app using the command line (firebase deploy), everything works fine.

Firebase.json

{
  "hosting": {
    "site": "flutter-ast-viewer",
    "source": ".",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "frameworksBackend": {
      "region": "us-east1"
    }
  }
}

.firebaserc

{
  "projects": {
    "default": "flutter-ast-viewer"
  }
}

I tried a bunch of other things but it seems like something gets broken in the GitHub action. Manual deploys work fine.

"error": "Must supply a "public" or "source" directory or at least one rewrite or redirect in each "hosting" config."

Error: Hosting configs should only include either "site" or "target", not both.

"error": "Can only specify "source" or "public" in a Hosting config, not both"

Error: Directory ‘build/web’ for Hosting does not exist.

    I have the same problem, this was my solution:
    On webindex.html look at this:
    [enter image description here][1]
    [1]: https://i.sstatic.net/wijVuZzY.png
    change

    <script src="flutter_bootstrap.js" async></script>

    for

    <script src="./flutter_bootstrap.js" async></script>

    I’ts because the path its wrong, that works for me
