multi vehicle error

[hwanyongpark]

Thank you for your offboard control example.
I tried your example in ROS2 humble & gazebo garden environment.
And I want to use your example for multi drones with instances like picture below.

It successfully spawn the drone and the codes.
And I changes the topic names with uav instances below.

But I tried to arm and control the velocity of the drone, but it doesn't move and arm.

So I checked rqt_graph, but node publisher and subscriber is connected like below.

So could you help how can i fix it?
