upload_to_testflight stucks waiting for the build to show up in the build list about fastlane

I've made this workaround to await build. And it works

puts "Waiting for build to appear in TestFlight..."
    attempt_count = 0

    loop do
        attempt_count += 1
        puts "Attempt #{attempt_count}. Check App Store Connect if it takes to long."
        sleep(60 * 5) # Wait for 5 minutes
        latest_build_number = latest_testflight_build_number(
              app_identifier: ENV["FL_APP_ID"],
              api_key: api_key,
              version: version_number,
              initial_build_number: 0
              )
        if(build_number == latest_build_number)
            puts "Build #{version_number} (#{build_number}) found, continuing..."
            break
        else
            puts "Build #{version_number} (#{build_number}) not found, latest build is #{latest_build_number}. Still waiting..."
        end
    end

Sorry, we've found mistake on our side. We forgot to change Apple ID for app after copying CI scripts to a new project. So I've closed this issue
