[emusman-lab]

Hello
when i launch the ros2 launch vrx_gz competition.launch.py world:=/home/usman/boat_ws/src/vrx/vrx_gz/worlds/gymkhana_task.sdf
I get the following errors

[ruby $(which ign) gazebo-1] [Err] [Server.cc:139] Error Code 13: [/sdf/world[@name="gymkhana_task"]/include[1]/uri:/home/usman/boat_ws/src/vrx/vrx_gz/worlds/gymkhana_task.sdf:L351]: Msg: Unable to find uri[coast_waves]

Not sure if my problem is related to yours, but I when I try to run the command from the tutorial I get this error:

ros2 launch vrx_gz competition.launch.py world:=sydney_regatta.sdf

when I try to start the sydney_regatta.sdf file manually ,without the launch file, i get the same error as emusman-lab.
"Msg: Unable to find uri[coast_waves]"

[create-3] [INFO] [1689234349.036520696] [ros_gz_sim]: Requesting list of world names.

I solved it myself by installing it through docker through following these two links
