Isaac Sim Pick And Place Operation

Hi everyone,
I’m a complete beginner and I’m working on a use-case to get to know Isaac Sim better. I’m trying to program a pick-and-place operation using the ‘Action Graph’ and transfer it to a real robot. I’m following this tutorial: OmniGraph: Pick-and-Place Controller Node — Omniverse IsaacSim latest documentation, but it’s not working for me even though I’m following the steps precisely. Also, I think this might not be the right approach since I’m not using any ROS nodes. Should I also use ROS2 Publish/Subscribe Joint State nodes for this? I would really appreciate any help with this issue 🙂
Thanks!
