I'm getting this error from inside the TestFlight tab in Appstore Connect. For a MacCatalyst app. This has worked for amost 4 years now I'm getting this error.
I did update my version of Xcode to 26.0.1. And I migrated all the project settings it asked me to migrate.
I ran the Validation in the Archive window of Xcode. No issues found there.
Thank you for your post.
Started happening on Xcode 26.0.1 or were you successful with that version of Xcode? Have you tried today to submit one to TestFlight? Do you have all the logs?
Could you create a bug report and provide me with the FB number?
Once you open the bug report, please post the FB number here for my reference.

To clarify, it works properly with an iOS app upload. It is only for MacCatalyst app. So Xcode 26.0.1 works for ios and not for MacCatalyst.
Have you tried today to submit one to TestFlight?
I have, twice, still been getting the same issue. I will try again later today.
Do you have all the logs?
I have the build logs. But it is too big to attach to this reply. I will add it to the bug report.
Thanks for doing this, please make sure to post the bug report for my records.
Thanks Albert Pascual Worldwide Developer Relations.

I attached the build logs to that report.
Thanks for providing this, I'll be able to track it.
