In my asp .net mvc application I wrote an action method to return JSON using action result return JSON method. And it was throwing this error To allow GET requests, set JsonRequestBehavior to AllowGet.

The solution was to modify the code and pass the second parameter JsonRequestBehavior.AllowGet

    var retval = new SetupIngredient(Common.ConnectionString).GetNameImage();
    return Json(retval, JsonRequestBehavior.AllowGet);
}
