The spatial tendon attachment 'L2' was not parsed, because its supposed parent was declared a leaf or could not be found

Hi, there, thank you for your attention, I have tried spatial tendon with isaac sim recently, but got stuck with the first step. I followd the physical scene demo to create a spatial tendon with revolute joint, but failed with the error:
“The spatial tendon attachment ‘L2’ was not parsed, because its supposed parent was declared a leaf or could not be found at /World/Cube_01.”

I have no idea about how to solve it, hope getting help from you, thanks!

My demo file is here, thanks a lot!

Hi @suxfj2, Thanks for sharing this issue and sharing the files to reproduce it. I will look into this shortly.

Hi @suxfj2, Sorry for the delay. I was able to reproduce the error. You need to create an articulation for the Spatial Tendon to work Physics Authoring Toolbar (PhysX Support UI) — Omniverse Extensions I have attached the asset with the articulation added. You basically select the base link (in this case was the transparent cube) and Add>Articulation Root.
