rosbag2 doesn't record turtlebot3 scan messages
To reproduce this, simply follow TurtleBot3's simulation tutorials and start it
$ ros2 launch turtlebot3_gazebo turtlebot3_world.launch.py
Confirm messages are sent with
$ ros2 topic echo scan
Try to record with
$ ros2 bag record scan -o tb3bag
And after a while, use info to check that nothing was recorded.
$ ros2 bag info tb3bag2

Am I doing something wrong? Or should this be reported in rosbag2's issues?
