Android CI/CD with Fastlane and GitHub Actions: "fastlane" command not found at master branch

Question

I'm trying to implement a CI/CD workflow for my Android project using Github Actions and Fastlane. I created a workflow to build and APK file and upload it to Firebase App Distribution. My workflow is triggered and succeed when I pushed to my development branch and uploads the APK file to Firebase App Distribution as expected.

But the same workflow is failed on master branch (without any code changes) with error: "bundler: command not found: fastlane"

When I call the same fastlane action on my local device, it works and uploads the APK to Firebase App Distribution.

Here is my lane:

    lane :beta do |options|

        version = options[:versionChange]
        runUnitTests = options[:runUnitTests]
        gitUserMail = options[:gitUserMail]
        gitUserName = options[:gitUserName]

        # 1- Make version code and name incrementation

        if version.nil? || version == 'patch'
            gradle(task: "doPatchVersionIncrement")
        end

        if version == 'major'
            gradle(task: "doMajorVersionIncrement")
        end

        if version == 'minor'
            gradle(task: "doMinorVersionIncrement")
        end

        gradle(task: "doBuildNumberIncrement")
        gradle(task: "doBuildNumberBetaIncrementValueIncrement")

        # 2- Run unit tests for all variants
        if runUnitTests.nil? && runUnitTests != 'false'
                gradle(task: "clean")
                gradle(task: "test")
        end

        # 3- Build Release APK
                gradle(task: "clean")
                gradle(task: 'assemble', build_type: 'Release')

        # 4- push version bump commit

        properties = property_file_read(file: "app/version.properties")
        versionMajor = properties['VERSION_NAME_MAJOR']
        versionMinor = properties['VERSION_NAME_MINOR']
        versionPatch = properties['VERSION_NAME_PATCH']
        versionCode = properties['VERSION_CODE']
        versionName = "#{versionMajor}.#{versionMinor}.#{versionPatch}"

        if !gitUserMail.nil? && !gitUserMail.empty? && !gitUserName.nil? && !gitUserName.empty?
              sh "git config --global user.email #{gitUserMail}; git config --global user.name #{gitUserName}"
        end

        sh "git add .. ; git commit -m 'Version bump : versionCode = #{versionCode} | versionName = #{versionName}'"
        push_to_git_remote

        # 5- Send APK to Firebase
        firebase_app_distribution(app: "MY_FIREBASE_APP_ID", groups: "qa-team")
  end

Here is my .yml file for GitHub Action:

name: Deploy Release APK to Firebase App Distribution

on:
  push:
    branches:
      - "**"
  pull_request:
    branches:
      - master

  workflow_dispatch:

jobs:
  upload_firebase_app_distribution:
    name: Upload to Release Apk to Firebase App Distribution
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/[email protected]

      - uses: ruby/setup-ruby@v1
        with:
          ruby-version: '2.6'
          bundler-cache: true

      - name: Distribute app with ???? App Distribution ????
        run: bundle exec fastlane beta version:patch runUnitTests:false gitUserMail:[email protected] gitUserName:user_name

Updated Ruby version
Installed Fastlane after Ruby
Added "android" command after "fastlane" command

Then problem is solved. Here is the fixed workflow:

name: Deploy Release APK to Firebase App Distribution
on:
  push:
    branches:
      - master
  pull_request:
    branches:
      - master

  workflow_dispatch:

jobs:
  deploy_to_beta:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2

      - name: Setup Ruby
        uses: ruby/setup-ruby@v1
        with:
          ruby-version: '2.7.2'

      - name: Setup Fastlane
        run: bundle install

      - name: Deploy to Firebase
        run: bundle exec fastlane android beta version:patch runUnitTests:false gitUserMail:[email protected] gitUserName:user_name
