Hi,
following the steps in the PX4-ROS2 guide (https://docs.px4.io/main/en/ros2/user_guide) and starting the PX4 Autopilot and Gazebo server with the command HEADLESS=1 make px4_sitl gz_x500 the process terminates with the error
terminate called after throwing an instance of 'eprosima::fastcdr::exception::BadParamException'
what(): This member is not been selected

Aborted (core dumped)

Instead, if I build and run inside a ROS2 Workspace following this guide (https://docs.px4.io/main/en/middleware/uxrce_dds#build-run-within-ros-2-workspace)
everything works well and the clients connects to the agent and I can receive the uORB messages and see the topics with ros2 topic list

How can I solve this problem using the 'Make installation' instead of using the 'Build and Run ROS2 Workspace installation'

Have you solved the problem? I'm thinking of switching to Zenoh
