Invalid or expired articulation handle

Hello,

I’m facing some issues importing URDF File in Isaac Sim 2023.1.1
I’m actually using the libray cuRobo follows a link to the tutorial:
https://curobo.org/tutorials/1_robot_configuration.html

I get these errors:

Follow the files I’m using:
try.zip (159.8 KB)

Basically I’m having issues at this step of the tutorial:


when the library uses a script to call the URDF importer of Isaac Sim.

I’m looking forward to find a solution.
Thank you in advance!!

Mattia
