error on custom object

I am observing the following error when running following the instructions here: 6. Offline Pose Estimation Synthetic Data Generation — Omniverse Robotics documentation

Here’s my blender test file and .usda export:
monkey.blend (936.0 KB)
monkey.usda (144.0 KB)

I’ve only changed “self.asset_path” and “part_name” in to point to this model file. Everything else is the same.
I can run the demo successfully with the original “003_cracker_box” object.
I can open the .usda file in IssacSim when running the GUI, so I don’t think it’s an issue with the model file.
I also tried the binary .usdc format.
IsaacSim v2022.2.0

I was able to fix this by creating a default ‘World’ prim in IsaacSim and saving the file.
