Client [/rviz_15....] wants topic /odom to have datatype/md5sum [sensor_msgs/PointCloud/d8....], but our version has [nav_msgs/Odometry/cd... Dropping connection.

edit

I’m getting this error: The robot launch file starts and all appears good. I start rviz then I get one Pose array dataset then this error

[ERROR] [1556066738.031123079]: Client [/rviz_1556066697211260013] wants topic /odom to have datatype/md5sum [sensor_msgs/PointCloud/d8e9c3f5afbdd8a130fd1d2763945fca], but our version has [nav_msgs/Odometry/cd5e73d190d741a2f92e81eda573aca7]. Dropping connection.

This message seems to indicate the required data type should be [sensor_msgs/PointCloud] However, all the ROS info seems to indicate the proper /odom data type is [nav_msgs/Odometry] At this time I suspect a AMCL or a RVIZ setup issue

Here is the AMCL launch file
