ROS-on-Windows-10 (melodic) spawn sdf model

edit

Hi,

I am trying launch a Gazebo Simulation and spawn a pillow. Which I got from here. https://bitbucket.org/theconstructcor...

After launching ROS stucks at Waiting for service /gazebo/spawn_sdf_model

started core service [/rosout]
process[pillow_spawn_urdf-2]: started with pid [14152]
[INFO] [1562321054.835000]: Loading model XML from file C:\catkin_ws\src\pillow_issue\models\pillow\model.sdf
[INFO] [1562321055.866000]: Waiting for service /gazebo/spawn_sdf_model

It works fine on ubuntu. I tried it on two Windows 10 Pcs both have this problem. Also I tried spawning a URDF which works fine.
