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
