GZweb isn't recieving map and robot model from Docker container

Question

I am trying to run a simulation environment as well as robot model which I didn't build it. So I dowlanded Docker Desktop on my Windows Home 10 and try to run this container called ayas-gazebo-1. In this container. It is supposed to run VNC and GZweb envireonment on the localhost via ports 8081 and 8080 respectively. While VNC environment seem to be workin fine, in GZweb the map isn't loading(only seeing empty grid). As you can see on the screenshots

VNC Environment on localhost 8081

Note: also you can observe that Robot Model isn't recieving properly as well as the camera data.

As I mentioned earlier GZweb supposed to load a whole map and Rovers itself.

GZweb Environment

I have been trying to run again and again container ayas-gazebo-1 but it seem to be having same problem. But I am not sure what kind of problem that I am facing.

Also I am attaching the only warning which I get ayas-gazebo-1 container's log which I run in Docker Desktop.

File "/home/catkin_ws/src/CMakeLists.txt" already exists[WARN  tini (73)] Tini is not running as PID 1 and isn't registered as a child subreaper.
Zombie processes will not be re-parented to Tini, so zombie reaping won't work.
To fix the problem, use the -s option or set the environment variable TINI_SUBREAPER to register Tini as a child subreaper, or run Tini as PID 1.

mkdir -p /home/catkin_ws/src
cd /home/catkin_ws/src/

cd /home/catkin_ws/
catkin_make

sh /src/rootfs/startup.sh

I have tried to connect the model directly Gazebo environment in Ubuntu but it didn't work. And also Ubuntu environment is too slow in my computer.

UPDATE I have achieved to eliminate other errors the only warning that I am getting is given above. So I made several researches but it didn't work.
