something went wrong...

Hello ! Firstly ,thank you for contributing the code.
but I am confused about the error after running the command like this:
ros2 launch roverrobotics_gazebo 4wd_rover_gazebo.launch.py ros2 launch roverrobotics_driver navigation_launch.py
the error is like:

Could you please tell me how to fix it?

I only configured this repo to use RL (SB3 and DreamerV3) for navigation so I would have to look into navigation_launch.py. Does ros2 launch roverrobotics_gazebo 4wd_rover_gazebo.launch.py work for you?
