I was getting a similar email everytime that I was trying to deploy the iOS app to the TestFlight by using FastLane and Circle Ci. In my case the problem was at the configuration of config.yml and at the fastlane version. Steps to fix this issue if you're using the fastlane and circle ci to deploy your app are like below: 1. Change the xcode version on your config.yml (macos: xcode: 14.1) then 2. change fastlane version to 2.210.0 otherways the fastlane will return an error for transporter.
