I follow the ROS2 tutorial, But the topic /cmd_vel don’t appear
And when I try to run the simulation I get the following error :
2023-01-10 09:15:01 [Warning] [omni.usd] Warning: in SdfPath at line 97 of /buildAgent/work/ca6c508eae419cf8/USD/pxr/usd/sdf/path.cpp – Ill-formed SdfPath <>: syntax error
that warning shouldn’t stop you from getting messages. Can you confirm that you’ve performed this ROS2 prep step before launching sim and enabling the ROS2 bridge? (where you need to specify the Fast DDS middleware and setting a few env variables): 6. ROS & ROS 2 Installation — Omniverse Robotics documentation
