When uploading apk with the Run wzieba/Firebase-Distribution-Github-Action@v1.3.2 I get the following error

I am trying to upload an apk to firebase using github action. I have commented out the code analysis and tests to make the action run faster so as to try and resolve the issue. I have also tried to upload an app bundle, I get the same response. Here is the github action configuration.

name: Deploy app bundle to firebase

on:
  push:
    branches:
      - dev

jobs:
  build:

      - uses: subosito/flutter-action@v1 # Setup flutter environment
        with:
          flutter-version: '2.5.0'

        with:

          groups: testers
          file: build/app/outputs/flutter-apk/app-debug.apk  

When I run the workflow I get the following error:

I had made a mistake on this line

- uses: actions/upload-artifact #This uploads artifacts from your workflow

The comment is correct but the action is wrong. I should have used actions/upload-artifact https://github.com/wzieba/Firebase-Distribution-Github-Action/issues/51
