Transform from base_link to map was unavailable for the time requested (error after running Robot_localizaton pkg))

edit

hi,

I use two instances of robot_localization pkg, because in my case the tf between odom->map will be provided by the vehicle (there is robot_localization pkg inside the robot, that publishes this frame already). now the problem, is that when i run the bag file, and run the robot_localization pkg, it shows me the following error:

[ WARN] Transform from base_link to map was unavailable for the time requested. Using latest instead.

how can i resolve this issue?

thanks
