Can't load custom assets into ISAAC sim

I am trying to load a custom asset from a python script using SimulationApp. I get the following error on trying to load the custom asset from the localhost:-

The same asset can be dragged and dropped onto a blank scene in Isaac SIM. I would really appreciate some suggestions.

I also have this problem!

@jay.anjankar can you share the usd asset and a minimal python script that reproduces the issue?

What API are you using to load the custom asset?

@jay.anjankar / @leila , as requested by Hammad in previous comment, can you please share the usd asset and minimal python script?

Hi Hammad and rthaker,
This is the script to recreate the issue related to loading of custom assets. The custom asset can be loaded locally (from the Desktop) but it cannot be loaded from inside the local server inside nucleus.
