Hi, I need to implement two method (one System.Web.Mvc.HttpGet and System.Web.Mvc.HttpPost) than allow anonymous.

My actual code is

    public class SpidController : DnnController
    {
        private ILog Log = LoggerSource.Instance.GetLogger(typeof(SpidController));

        [AllowAnonymous]
        [HttpGet]
        public string SpidCallback(string data)
        {
            return data;// Json(new { cf = data }, JsonRequestBehavior.AllowGet);
        }

        [AllowAnonymous]
        [HttpPost]
        public string SpidCallback()
        {
            return "mydata";
        }
    }

I try with Postman (myurl/DesktopModules/MVC/DizionariCondivisiSpidApi/Spid/SpidCallback) and if I don't pass ModuleId and TabId I receive this error

Object reference not set to an instance of an object.

[NullReferenceException: Object reference not set to an instance of an object.]

Thanks for the help,
