[BUG] Cannot Deploy Angular App To Firebase Hosting

[lisk8]

Hello,

I can't deploy my Angular application either by CI/CD or CLI command.
This worked a while and after a while it started showing the error...

The angular application runs without any errors when serving it.

Action config

name: Deploy to Firebase Hosting on merge
'on':
  push:
    branches:
      - main
jobs:
  build_and_deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - run: npm i && npm run build
      - uses: FirebaseExtended/action-hosting-deploy@v0
        with:
          repoToken: '${{ secrets.GITHUB_TOKEN }}'
          firebaseServiceAccount: '${{ secrets.FIREBASE_SERVICE_ACCOUNT_MY_HOSTING }}'
          channelId: live
          projectId: my-hosting
        env: 
          FIREBASE_CLI_EXPERIMENTS: webframeworks

or

firebase deploy --only hosting

Error message

Hi, I got the same errors as you. Here it is my workflow:

name: Deploy to Firebase Hosting on merge
'on':
  push:
    branches:
      - main

jobs:     
  build_and_deploy:
    name: Build then deploy to Firebase Hosting
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Git Repo
        uses: actions/checkout@v3
      - name: Use Node.js 20.1.0
        uses: actions/setup-node@v3
        with:
          node-version: 20.1.0
      - name: npm install, build
        run: |
          npm install
          npm run build
      - name: Install Firebase CLI
        run: |  
          npm install -g firebase-tools
          firebase --version
      - name: Deploy to Firebase
        run: |
          echo '${{secrets.FIREBASE_SERVICE_ACCOUNT}}' > $HOME/gcloud-service-key.json
          export GOOGLE_APPLICATION_CREDENTIALS="$HOME/gcloud-service-key.json"
          firebase deploy --only hosting

and if you are building a SPA, make sure that your firebase.json file look like this:

{
  "hosting": {
    "public": "dist/your-app-name",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "frameworksBackend": {
      "region": "europe-west1"
    },
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  }
}

Thank you @JuHue this solution helped me too with my Angular 17 app. I use your code up until & incl.
- name: Deploy to Firebase
Merge workflow now works.
Thank you @lisk8 for posting the issue - discussions like this help beginners like me.
