isaac_ros_map_localization ERROR : Got a scan that has FOV 106 smaller that threshold 270

Hello , I have been exploring the use of this package. I am getting the following error. ERROR extensions/localization/flatscan_localization/grid_search_localizer.cpp@306: Got a scan that has FOV 106.000000 smaller than threshold 270.000000, ignoring this scan.

My scans are clipped not to see the back of the robot , ~300 FOV. The angle ranges in the flat scan does look right from -3.0 to + 3.1. Sandeep

It looks like the FOV is computed to be 106 from the FlatScan msg. Can you please post the FlatScan msg for this error comes up?

Hello Ashwin, Is there a way to capture the scan that caused the problem ? If I capture all scans it will be large. Sandeep

If you can provide a small rosbag + map(.png+.yaml) and launch file, I can try to reproduce this on my end. Then I look into it this issue further.

sorry about the delay .I have attached a rosbag and the map. Please let me know if you anything else to reproduce. rosbag.zip "map.yaml" image: upper_corridor.png mode: trinary resolution: 0.05 origin: [-2.94, -1.64, 0] negate: 0 occupied_thresh: 0.65 free_thresh: 0.25
