Error with range_sensor_layer. move_base node dies when a sensor_msgs/Range is published [closed]

Hi, I am trying to setup a range_sensor_layer to use an ultrasonic sensor on the navigation stack. I am using 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 one RGB-D camera and an ultrasonic sensor.

First I launch the navigation without publishing sensor_msgs/Range on its topic. Then I can navigate without the ultrasonic data. When I launch the node that publishes the Range data, the move_base node dies.

Can anybody help me to configure correctly the range_sensor_layer?

Following are my configuration files:

global_costmap_params.yaml

global_costmap:
  global_frame: map
  robot_base_frame: base_footprint
  update_frequency: 0.5

I have no idea what is causing it, but those bounds look highly suspect to me. They look like uninitialised memory of doubles, or perhaps even integers interpreted as doubles, or something else that's wrong there.

I would first fix that before suspecting the sonar messages.

Thank you for your response @AlexM. I tried to use the code from github https://github.com/DLu/navigation_layers using git clone and it worked.
