Open

Could you please explain in detail how to make a topic and message readable by ROS2?
I want to visualize another ros message in RViz,

I add rt/ in front of the topic
I use default Qos,

I used rtiddsgen with c++11,
I can see topic in ROS2

However when I echo the topic to see message
ros2 topic echo /topic_name

I got an error
The passed message type is invalid.

Thanks in advance
