Not Driving Turtlebot via ROS2 messages

Hi there,

I am using Isaac Sim 2023.1.1 & ROS2(humble) on Ubuntu 22.04.4 LTS. I am trying to control turtlebot via ROS2 messages but I have an error as follows:

When I start the simulation, the articulation controller gives a warning. “OmniGraph Warning: Prim path expression is invalid, a prim matching the expression must be created before wrapping it as a view”.

I have watched this video(livestream) and applied this step, but the error still continues.

Could you please help me with this error?

Best wishes

Did you find any solution, I’m facing the same issue.
