Hello,

I am trying to run the ydlidar_ros2_driver package using the ydlidar_launch.py file but I am encountering some errors. Below is the error message I receive:

Additionally, I also tried running the ydlidar_launch_view.py file and encountered a similar issue. Here is the error message for that:
