Ionic cordova build aandroid --release aab "Web page not available"

Question

I created a simple ionic app, works good if i build with --packageType=apk and install it to the phone or run with --livereload but when i build it locally without --packageType=apk or run the pipeline on git actions the app will show this error:

this is the pipeline:

name: android_build

on:
  push:
    branches:
      - main

jobs:
  build:
    name: Build APK
    runs-on: ubuntu-latest
    steps:
      - name: Checkout source
        uses: actions/checkout@v2

      - name: Setup java
        uses: actions/setup-java@v1
        with:
          java-version: 1.8

      - name: Setup Android SDK
        uses: android-actions/setup-android@v2

      - name: Setup Node.js
        uses: actions/setup-node@v1
        with:
          node-version: 16.x

      - name: Install Cordova
        run: npm install -g cordova

      - name: Install Ionic
        run: npm install -g @ionic/cli && npm i -g cordova-res

      - name: Install app dependencies
        run: npm install

      - name: Add resources
        run: ionic cordova resources

      - name: sdk version
        run: sdkmanager --uninstall 'build-tools;31.0.0' && sdkmanager --uninstall 'build-tools;32.0.0' && sdkmanager "build-tools;30.0.3" "platforms;android-30"

      - name: Add Android platform
        run: ionic cordova platform add android

      - name: Build Android Release APK
        run: cordova build android --release --prod -- --keystore=./app-mobile.keystore --storePassword=${{ secrets.KEYSTORE_PASS }} --alias=app-mobile --password=${{ secrets.KEYSTORE_PASS }}

      - name: Upload APK
        uses: actions/upload-artifact@v1
        with:
          name: app-release.aab
          path: platforms/android/app/build/outputs/bundle/release/app-release.aab

on ios works good,

any hints?

thanks

update: when adding ionic cordova prepare android before build everything works as expected
