roslaunch error. Resource not found: xacro #137

Context

Please provide any relevant information about your setup.

I was doing tutorial six. To verify GAAS-Object-Tracking by completing make-j4, roslaunch px4 car_tracking.launch was performed. But it didn't work out as an error.

roslaunch px4 car_tracking.launch
