Hi all,

I got this error while running vslam-tutorial.bag and of course it can't run

Waiting 0.2 seconds after advertising topics... done.

Hit space to toggle paused, or 's' to step.

Client [/wide_stereo/stereo_vslam_node] wants topic /wide_stereo/right/camera_info to have datatype/md5sum [sensor_msgs/CameraInfo/c9a58c1b0b154e0e6da7578cb991d214], but our version has [sensor_msgs/CameraInfo/1b5cf7f984c229b6141ceb3a955aa18f]. Dropping connection.

How can I solve this problem?
