I exported urdf from usd. There was no problem with urdf. Why did such a problem occur?

Could you please try the newly released Isaac Sim 4.2.0 and let us know if you still encounter any problems?

Hi I’m currently getting the same error on 4.2.0. Tested with an URDF I generated myself and one from the omni.isaac.motion_generation/motion_policy_configs/ path.
