world file

<?xml version="1.0"?>
    <sdf version="1.6">
      <world name="default">
        <include>
          <uri>model://ground_plane</uri>
        </include>
        <include>
          <uri>model://sun</uri>

              </geometry>
            </visual>
          </link>
        </model>
      </world>
    </sdf>

this is file

<launch>
  <include file="$(find gazebo_ros)/launch/empty_world.launch">
    <arg name="world_name" value="city.world"/>
    <arg name="verbose" value="true"/>
  </include>
</launch>

this is my launch file

when I launch this it shows me an error as

[Err] [Server.cc:379] Could not open file[city.world]

but when spawn using

gazebo city.world

there is no error and it's spawning correctly. what could be the problem?

Thanks, that was the problem

but now when I'm trying to launch it gives this error

[Wrn] [FuelModelDatabase.cc:248] URI not supported by Fuel [model.dae]
[Wrn] [SystemPaths.cc:464] File or path does not exist [""] [model.dae]

maybe you also need to set the path of model.dae... like this:

          <geometry>
        <mesh>
          <uri>model://iscas_museum/meshes/ISCAS_museum.dae</uri>
        </mesh>
      </geometry>enter code here
