The remote computer rviz could not display cloudmap in rostopic rtabmap_ros/MapData. But in my locobot computer the rviz can display cloudmap. #856

When I rostopic echo rtabmap_ros/MapData, there is not data. But the other rtabmap topics have data. And the rostopic list is well, has rtabmap_ros topics. At the same time, the error in locobot terminal which is [ERROR] [1671167054.638756074]: Client [/rostopic_31925_1671167054167] wants topic /locobot/rtabmap/mapData to have datatype/md5sum [rtabmap_ros/MapData/e20572a812f1f74060a7f5d1a39f9106], but our version has [rtabmap_ros/MapData/8f9b7a6a9f675febbbe86bf0926d6fcd]. Dropping connection.

For the error, it means your robot is not using the same rtabmap version than the remote computer. The msg has been updated.
