404 not found: could not find the controller.
I've manually confirmed Services are set up properly with Advanced REST client (Chrome), with this instructions. All seems OK; the endpoint/resource is operating and I receive a 200 OK response, but when I try to test the application from admin/config/services/drupalgap, I always get this error.
I use Services frequently and I can confirm It's working good on this site. I also verified DrupalGap is working too.
What could it be?
