Hello

I wrote such code to test restAPI client:

///////
//app.d
///////

import vibe.d;
import sites.frontpage;
import msfrontpage;

shared static this()
{
	// the router will match incoming HTTP requests to the proper 
routes
	auto router = new URLRouter;

	// registers each method of WebChat in the router
   auto api = new 
RestInterfaceClient!IfFrontPageAPI("http://127.0.0.1:8090/");
	router.registerWebInterface(new SilesianCloud(api));
	// match incoming requests to files in the public/ folder
	router.get("*", serveStaticFiles("public/"));

	auto settings = new HTTPServerSettings;
	settings.port = 8080;
	settings.bindAddresses = ["::1", "127.0.0.1"];
	listenHTTP(settings, router);
	logInfo("Please open http://127.0.0.1:8080/ in your browser.");
}


//////////////
//frontpage.d
//////////////
module sites.frontpage;


import vibe.d;
import msfrontpage;



final class SilesianCloud {

   this(RestInterfaceClient!(IfFrontPageAPI) tmp)
   {
       this.frontpageapi = tmp;
   }

   public:
   // GET /
   void get()
   {
     Json result = frontpageapi.getHome();
     logInfo(result.toString);
     auto header = result["heading"].get!string;
     logInfo(result["heading"].get!string);
     render!("frontpage.dt",header);
   }

   private:
     RestInterfaceClient!(IfFrontPageAPI) frontpageapi;
}

But it looks like my value is not "extracted" from Json in proper 
string, even logInfo(header) shows "nothing" and in web broser im 
getting:

500 - Internal Server Error

Internal Server Error
