The errors you listed (LibraryUnloadException) are a known issue when disposing of a MoveGroup object (see here), but should not affect the observed planning or execution.

Check the terminal window in which you launched the move_group node (not the same window as above) for additional error messages. Are you sure that the planning was completed successfully? The ROS-I tutorial you reference tries to move the robot to a random joint position, which is not always reachable by the robot. You may see failure messages related to "unreachable position" or similar.
