Error sending json via $http

Question

I am trying to send a json via $http.get, but it is returning an error in the console "500 (Internal Server Error)" system.technology.Ws/pedidGravar.Asp:1 Is this error in ASP system or $http request? Follow the requisition code

    $http({
       method: 'GET',
       url: 'http://sistema.tecnologia.ws/pedidoGravar.asp',
       data: JSON.stringify($scope.recuperaSeuPedido),
       headers: {'Content-Type': 'application/json'}
     }).then(function successCallback(response) {
         console.log(response.data)
         console.log("enviou");
       }, function errorCallback(response) {
         console.log(response.data)
         console.log("nao enviou");
       });

I disabled $http and did it in pure js and returns the same error. Follow the code below

   xhr = new XMLHttpRequest();
     var url = "http://sistema.tecnologia.ws/pedidoGravar.asp";
     xhr.open("GET", url, true);
     xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded; charset=UTF-8");
     xhr.onreadystatechange = function () {
         if (xhr.readyState == 4 && xhr.status == 200) {
             console.log(xhr.responseText);
         }
         console.log(xhr.responseText);
     }
     xhr.send("json=" + encodeURIComponent(JSON.stringify($scope.recuperaSeuPedido)));
