No output: sensor_combined_listener.launch.py

Hello everyone. My name is Joonmo, and I have questions.I have been following ROS 2 User Guide (PX4-ROS 2 Bridge) from px4 document for Gazebo simulation.
I am facing the issue that " ros2 launch px4_ros_com sensor_combined_listener.launch.py " is not giving output. I think micrortps_agent is not publishing information to topic.

  1. Do you guy have any idea to fix this?
  2. Which repo or code should I look at?
  3. I also ran “micrortps_agent -v -t UDP”, and output was something with “RTTI too high and offset not updated.” what does this mean?

micortps_agent_-v_-t_UDP
