URDF exporter error

Hi, I am trying to export URDF from the USD files. Then for some of my files, I got the following message. But it really looks like a float numerical error instead of a not-supported USD->URDF conversion. Any suggestions? Appreciate it!

2024-04-01 23:59:57 [Error] [omni.ui.python] RuntimeError: URDF cannot scale radius axes different amounts. Cylinder ‘/walker_01/torso/right_foot/collisions/right_foot’ has scaling factors of 0.9999999657714591 and 1.0000000000000002 for non-height axes.
