Multiple vehicle spawn error in ROS2 condition

[eogks465]

Hello everyone,

I’m trying to spawn muliple iris_depth_camera vehicle in SITL
I followed below document.

Multi-Vehicle Simulation with Gazebo Classic | PX4 User Guide (main)

When I tried to build that, I met the error

[ERROR] [1705243878.281362595] [gazebo_ros_node]: Found multiple nodes with same name: /camera_controller. This might be due to multiple plugins using the same name. Try changing one of the the plugin names or use a different ROS namespace. This error might also result from a custom plugin inheriting from another gazebo_ros plugin and the custom plugin trying to access the ROS node object hence creating multiple nodes with same name. To solve this try providing the optional node_name argument in gazebo_ros::Node::Get() function.

software versions are below.

gazebo version : classic
ROS2 version : ROS2 humble
PX4 version : 1.14.0 stable

Please give me any advice or ideas to solve the problem.
Thank you.
