xcrun usdz_converter issues after Xcode 10.1 update

Question

Before updating Xcode today I was able to convert .obj files to usdz without any issue. I have tried searching the internet and even turning it off and back on again. Has anyone else ran across this issue before?

$ xcrun usdz_converter ~/Desktop/obj_file/demo.obj ~/Desktop/obj_file/demo.usdz -v -a -l

Yes, we're seeing this too. It appears(?) to be harmless, but if you encounter any issues beyond the warnings please let us know (bugreporter.apple.com).
