Why is Xcode Cloud archiving failing?

I'm trying to build an Xcode Cloud workflow, but I keep getting this error. At first it just said I had to accept a license agreement, which I did, but it still didn't work after.

I had recently added a new branch to the connected GitHub repository and committed to it so that I can have a beta branch separate from the main one.

The only error that happens is when archiving.

I am using Xcode 27 beta.
