HttpService POST json - Error #2032

Question

Hi,
I'm trying to POST json data to my Rest Service (please find code snippet below). On the faultHandler I get the following error
message    "faultCode:Server.Error.Request faultString:'HTTP request error' faultDetail:'Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: https://135.123.128.9/mgmt/Users"]. URL: https://hostname/mgmt/Users'" 
<code>
     private function clickHandler(event:ItemClickEvent):void {
                    var user:User=new User();
                    user.loginName= login.text;
                    user.surname= lastName.text;
                    user.givenName= firstName.text;
                    user.userPassword=password.text;
                    createUserHttpService.contentType="application/json";
                    createUserHttpService.send(JSON.encode(userCopy));
      <mx:HTTPService id="createUserHttpService" 
                      useProxy="false" method="POST" result="userByUserIdServiceResultHandler(event);"
                       url="https://135.123.128.9/mgmt/Users"   fault="createUserServiceFaultHandler(event);" showBusyCursor="true" />                 
</code>
Thanks in advance

Answer 1

#1 - yes
#2 - yes, but im able to do GET on the same server and also POST for  content-type="text".
Can there be something specific if content-type="application/json" and POST  ?
Alternatively if someone can provide me a small code snippet which sends  json in the body of a POST request using HttpServic, that would be great as  well.. may be im missing something my code
Thanks
