Hi @pmginvestda6z, thanks for reaching out. This error is not anything you have done wrong, we are currently experiencing an issue with Apple that can cause some builds to fail. Our publishing team is currently working to alleviate the issue.
I will keep you updated here as we learn more and when the issue is solved. Thanks for your patience!
Thank you for your answer, I hope the this will be solved soon since we need to publish the app and we have paid both you and apple in order to do this.
