Hi, i have this spawn_burger.launch file. it loads a world i made, and a i am trying to spawn a tb3 burger to the world, i already installed tb3 packages and i tried this locally and it works, but when i try to run it on the RDS the tb3 burger won’t apear. the shell says that is loaded but i can no see it. Does anyone knows what i am missing?

<!-- from parameter server spawn model into gazebo -->
