Hi everyone,
I am trying to visualize lidar point cloud in RViz. I edited airsim_ros_wrapper.cpp as indicated in #2808. But i get this error in RViz:

In my settings.json I declared lidar like this:
"Lidar1": {
"SensorType": 6,
"Enabled": true,
"NumberOfChannels": 16,
"PointsPerSecond": 10000,
"DrawDebugPoints": false,
"DataFrame": "VehicleInertialFrame" }
I can get data from Lidar sensor, but I cannot visualize it in RViz. When I check data using "rostopic echo", I get this:

The frame_id is 1, as seen in the image above. I reviewed "airsim_ros_wrapper.cpp". But I did not see something like Frame 1.
Can you help me to solve this problem, please?
