I can't seem to shake this fastlane issue on GitHub actions: " Your Ruby version is 3.0.2, but your Gemfile specified 2.7.7"

I have been building my mobile pipelines both react-native and flutter pretty much the normal way. I am trying to get this first time fastlane pipeline up and so far it's been a bit rough. It's a react-native project with both android and iOS folders. I am following this blog https://blog.logrocket.com/fastlane-build-test-ship-react-native-apps/ so my setup is similar. Just that I am doing a firebase distribution lane. On the GitHub action, the actions/setup-ruby@v1 has been replaced by ruby/setup-ruby@v1.

The build always fails with the following even when a set like : ruby --version still shows 2.7.7

/opt/hostedtoolcache/Ruby/2.7.7/x64/lib/ruby/gems/2.7.0/gems/bundler-2.2.27/lib/bundler/definition.rb:441:in `validate_ruby!': Your Ruby version is 3.0.2, but your Gemfile specified 2.7.7 

Been scratching my hair for the past few hours on what I could be possibly doing wrong. Below is the GitHub actions

name: Android developer build

          ANDROID_KEYSTORE_KEY_ALIAS: ${{ secrets.DEV_ANDROID_KEYSTORE_KEY_ALIAS }}
          FIREBASE_DIST_GROUP: dev-android

The main Fastfile looks like the following

platform :android do
desc "This is a dev release, we will call it alpha"

    lane :alpha do
        increment_version_code(app_project_dir:'./android/app')
        increment_version_name(app_project_dir: './android/app', bump_type: 'patch')
        gradle(task: 'clean',project_dir: './android')
        gradle(task: 'assemble', bundle_type: 'Release', project_dir: './android', properties:{
            "android.injected.signing.store.file" => ENV['ANDROID_KEYSTORE_FILE'],
            "android.injected.signing.store.password" => ENV['ANDROID_KEYSTORE_PASSWORD'],
            "android.injected.signing.key.alias" => ENV['ANDROID_KEYSTORE_KEY_ALIAS']   
    })
        output_path = "./android/app/build/outputs/apk/"

        firebase_app_distribution(
            app: ENV['FIREBASE_APP_ID'],
            firebase_cli_token: ENV['FIREBASE_CLI_TOKEN'],
            groups: ENV['FIREBASE_DIST_GROUP'],
            release_notes: "Git commit: #{last_git_commit[:abbreviated_commit_hash]}",
        )
    end
end

If you do not want to deep dive you can try to change ruby version to 3.0.2 in your actions file or in your .ruby-version file and Gemfile
