Hi, I am trying to merge 3 (quanergy M8) lidar point cloud feed. So, I have update laserscan_topics in launch file, and then check all topic data by using rostopic echo. But when I tried to check merged cloud data it is not publishing any thing.

Listed all topics Lidar_topic

process[laserscan_multi_merger-1]: started with pid [6802]

In graph multi_merger node is not subscribing 3 lidars even though I mention in Launch file. rosgraph

Any Suggestion why node is not subscribing data?
