In version 5.5.0, if you look at the request window, there is a menu along the bottom. If you open the WS-A tab, you should see an "Add default was:To" option. Click that and re-run the request. I cannot say if the menu or setting is in the same location for other versions. I had 2 services running on the same server, one of them ran without this option checked, the other would not. I'm not sure why this variance occurred.
