Prim path expression /World/ur10_instanceable is invalid, a prim matching the expression needs to be created before wrapping it as view

[voll.olga.ds]

Hello together

I have installed the framework OmniIsaacGymEnvs and added the required files for UR10 Reacher, based on the package OmniIsaacGymEnvs-UR10Reacher. After I try to run UR10Reacher task, I get the following error:

Exception: Prim path expression /World/ur10_instanceable is invalid, a prim matching the expression needs to be created before wrapping it as view.

To follow, also a screenshot

Should I initialise the prim match first? But everything looks correct in the code.

Could someone help me with this?

Not precisely; I have used the ready USD file. I am now trying this tutorial.
