rtabmap/rtabmap-viz process has died

Hi, I am new to ROS, I don't fully understand PX4 and rtabmap packages but what I was able to successfully build rtabmap and rtabmap_ros and with also install PX4 and mavros/mavlink. Additionally, I was able to do the commands in the dockerfile

gazebo.launch was successful but when I try to run slam.launch it says rtabmap/rtabmap-viz process has died with exit code -6

How did you launch rtabmap_viz? Did you follow all docker commands? When opening a new terminal, don't forget to call again xauth lines.
