Error while generating synthetic data using Isaac Sim 2023

Omniverse Isaac Sim
1

Hello,

I used to generate synthetic data from a couple of scenes I had previously built. The generation was working fine on the previous version of IsaacSim. However, when I moved to IsaacSim 2023, some scenes are giving me the following error during the generation:

I am currently using the as base image IsaacSim 2023, and I am using a custom writer to output the dataset the format I need.

Can you please support me with this problem, and how can I fix these usd scenes that are not working fine with the new IsaacSim version

@toninsemaan just brainstorming here - looks like there is an issue related to OmniGraph, is there one in your scene? if so, are there any visible error from the node tree view?

Can you provide a short repro of the script you are running. It seems the error occurs at rep.create.camera. What arguments are you providing the function?
