free_fleet_server_ros2 ISSUE

edit

Hi everyone, i am following Free fleet tutorial in ROS2. After launch a ROS1 client and a ROS2 client, i launch a ROS2 server by ros2 launch ff_examples_ros2 fake_server.launch.xml, but the server node just inform

registered a new robot: [fake_ros2_robot]

registered a new robot: [fake_ros1_robot]

and an ERROR log (like the log part) then it died. I have read the server launch file and it just launch the node free_fleet_server_ros2. Then i run the free_fleet_server_ros2 directly. The problem did not change. It just informed as before, but did not show the ERROR log.

registered a new robot: [fake_ros2_robot]

registered a new robot: [fake_ros1_robot]

Can you tell me how to solve this issue please!

log part :

[INFO] [launch]: Default logging verbosity is set to INFO

[INFO] [free_fleet_server_ros2-1]: process started with pid [131280]
