There are 2 Surface Pro devices in the list at
https://github.com/fastlane/frameit-frames/tree/gh-pages/latest

It seems there is no matching code in
https://github.com/fastlane/fastlane/blob/master/frameit/lib/frameit/device_types.rb
?
Note that I am new to fastlane... maybe I am missing something?

Thanks
