offline mapping with slam_toolbox does not publish /map
Hi everyone,
I am trying to obtain an offline map by using slam_toolbox with the F1TENTH car. Setup on the car is ros foxy and ubuntu 20.04
First, I collected rosbag of all topics by ros2 bag record -a
Then runned the offline_launch.py of slam_toolbox and played the recorded bag file. On rviz, I can see the movement of base_link, however there is a warning on map display saying No map received.
When I echo /map topic, it does not show anything so I guess slam_toolbox does not publish any data to it.
Am I missing a step or doing something wrong while trying to create an offline map? Any help would be much appreciated since I cannot find any documentation regarding the offline mapping of slam_toolbox and there seems to be not much information on google regarding this topic.
