ROS Bridge error: 1 package had stderr output: pcl_recorder

[linpanusst]

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.

Task exception was never retrieved future: <Task finished name='Task-2' coro=<LaunchService._process_one_event() done, defined at /opt/ros/foxy/lib/python3.8/site-packages/launch/launch_service.py:226> exception=TypeError("Allowed value types are bytes, bool, int, float, str, Sequence[bool], Sequence[int], Sequence[float], Sequence[str].

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.
