Errors with Articulation Inspector while moving a robot, imported from an external urdf

When I open the Articulation Inspector to inspect the robot joints, I get the following warning repeatedly, eventually causing the simulation to stop due to the huge number of warnings:

[Warning] [omni.isaac.core.articulations.articulation] get_joint_efforts is deprecated. Please use get_applied_joint_efforts to get the applied joint efforts.

In addition, I have imported a robot from a urdf file to Isaac Sim. When I use the Articulation Inspector, I have many different errors:

I have similar errors also with Gain Tuner with Lula robot Description Editor, I do not know if they are all related. It could be that something is wrong with the urdf of the robot.usd file.

Any idea what could be wrong? Note: I am running Isaac Sim on a docker container.

Hello! We have an updated version 2023.1. Can you check if this error still persists?

Thanks

I think these errors disappeared with 2023.1.0; thanks a lot!
