When launch author's aruco_mapping(not the original aruco_mapping) on Ubuntu16.04 + ROS(kinetic), add a Marker in RVIZ, outputs:

[ERROR] [1572071396.201426506]: Client [/rviz] wants topic /aruco_markers to have datatype/md5sum [visualization_msgs/Marker/4048c9de2a16f4ae8e0538085ebf1b97], but our version has [visualization_msgs/Marker/18326976df9d29249efc939e00342cde]. Dropping connection.

aruco_mapping.launch content is:

  <include file="$(find realsense2_camera)/launch/rs_camera.launch" />

  <node pkg="aruco_mapping" type="aruco_mapping" name="aruco_mapping" output="screen">
    <remap from="/image_raw" to="/camera/color/image_raw"/>
    <param name="calibration_file" type="string" value="$(find aruco_mapping)/data/realsense_d435_rgb.ini" /> 
    <param name="num_of_markers" type="int" value="1" />
    <param name="marker_size" type="double" value="0.205"/>
    <param name="space_type" type="string" value="plane" />
    <param name="roi_allowed" type="bool" value="false" />
  </node>   
</launch>

I also tried the original aruco_mapping, also meeting the same error. When google this similar problem, they are caused by played ros bag, which recorded on different ROS version from the current playing ROS version, like here, any idea, thanks a lot!
