Can't get Xcode Cloud to work

I have an app I am toying with and I am seeing the following error in github's Xcode automation from Apple. My other apps work fine fine in xcode cloud with the same project setup.

Run scheme_list=$(xcodebuild -list -json | tr -d "\n")

What version of Xcode is your workflow configured to use? Xcode 16.2 should be able to build using this project file version.

You can also adjust the project file version to something older by opening it in Xcode 16.2, selecting the project file node in the project navigator, and looking for the Project Format dropdown in the File Inspector (on the right side of the Xcode window).
