range_sensor_layer creates a warning "Illegal bounds change, ... The offending layer is local_costmap/inflation_layer"

Hi, I am using ROS navigation stack (move_base) in a custom mobile robot. The robot uses a computer with Ubuntu 18.04.2 LTS and ROS Melodic (1.14.3). I am using a rgbd camera and a ultrasonic sensor.

When I setup to use plugin range_sensor_layer a warning appears in navigation launch log. The warning is "Illegal bounds change, ... The offending layer is local_costmap/inflation_layer".

Does anybody know why this warning appears? What means this warning?

When I disable the range_sensor_layer, the warning disappears. The topic that receives the range_sensor data is working good.

I can navigate with the robot regardless of the warning message. But when I comment the line of range_sensor_layer plugin in local_costmap_params.yaml, the warning is not shown.

local_costmap_params.yaml (with no warning):

...
plugins:    
    - {name: obstacle_layer, type: "costmap_2d::VoxelLayer"}       
    #- {name: sonar_layer,   type: "range_sensor_layer::RangeSensorLayer"}
    - {name: inflation_layer, type: "costmap_2d::InflationLayer"}

As I wrote in #q325716: those bounds look very suspicious. I'd figure out where they come from.

Thanks for your comments @gvdhoorn. Unfortunately, I have no idea how to debug this warning.

Can you check whether you have the latest version of all packages installed? If you did a partial update there could be an ABI problem causing strange things.

Previously I did sudo apt-get update and sudo apt-get upgrade. To confirm I did both commands again, upgraded all packages and the warning persists.

Hello. I tried to make theese changes but the warning still persists. Any additional change that should work?

Worked for me. Also don't forget to rebuild the package
