ROS Bridge error: 1 package had stderr output: pcl_recorder
When I use ros bridge and carla. I faced some problems. When I just start the example on the official document. Run the command ros2 launch carla_ros_bridge carla_ros_bridge_with_example_ego_vehicle.launch.py . I faced the error messages below.

I hope this discussion would help you. https://github.com/carla-simulator/ros-bridge/issues/601
I am using Ubuntu 20.04 with ROS2 galactic. When colcon building the ros bridge workspace I encounter the same warning:

could you solve it?
I'm a bit late, but for me doing
sudo apt install ros-melodic-pcl-ros
sudo apt install pcl-tools
solved the problem.
