On my turtlebot2 I roslaunch turtlebot_navigation gmapping_demo.launch, I get this error:

[ WARN] [1648588592.734240437]: Timed out waiting for transform from base_footprint to map to become available before running costmap, tf error: canTransform: target_frame map does not exist. canTransform: source_frame base_footprint does not exist.. canTransform returned after 0.101058 timeout was 0.1.

I have tried uninstalling and reinstalling the ros-kineitc turtlebot packages and it didnt work. I have no idea whats going on. I dont know why I've been having tf issues.
