AttributeError: 'NoneType' object has no attribute 'dock_in' when running start_isaac_sim_franka.py from tutorial

Hi NVIDIA Isaac ROS team,

Thank you for the excellent cuMotion + MoveIt integration tutorial
I was able to successfully run the "Using the cuMotion Planner in MoveIt" section of the tutorial.

But,
While following the tutorial at: "https://nvidia-isaac-ros.github.io/concepts/manipulation/cumotion_moveit/tutorial_isaac_sim.html"

specifically this step:
"Run python.sh with the full path to the start_isaac_sim_franka.py script provided by the isaac_ros_cumotion_examples package..."
I encountered the following error when running:
./python.sh /start_isaac_sim_franka.py

Error:
AttributeError: 'NoneType' object has no attribute 'dock_in'

I confirmed that:
I had set ROS_DOMAIN_ID=0 before execution.
I launched Isaac Sim using the official 4.5.0 release.

Please advise on how to proceed or whether this script should be updated for Isaac Sim 4.5.0 compatibility.

Thanks again,
