How to fix problem with sendJsonRequest promise in connectdialog.js?

[#1]

I've made several little changes in my connector and now it can't send JsonRequest to server.

$scope.onTestConnectionClicked = function () {

     console.log("testConnection init");

     var promise = input.serverside.sendJsonRequest("testConnection", $scope.username, $scope.password);

     console.log(promise);

     console.log("testConnection promise generated");

     promise.catch(function(a) {

         console.log("Catched ex");

         console.log(a);

     });

     promise.then( function ( info ) {

        $scope.connectionInfo = info.qMessage;

       $scope.connectionSuccessful = info.qMessage.indexOf( "OK" ) !== -1;

    } );

  };

Error I get, when onTestConnectionCliked function fires:

Error from Engine: Object {jsonrpc: "2.0", id: 51, error: Object}

Error object: code: -1 message: "Unknown error" parameter: "General exception"

My HandleJsonRequest method, from class QvAmoCrmServer (extends QvxServer)

(Two implementations, same effect)

First one:

      public override string HandleJsonRequest(string method, string[] userParameters, QvxConnection connection)

        {

            QvDataContractResponse response;

            QvxLog.Log(QvxLogFacility.Application, QvxLogSeverity.Debug, "Handle json Request > " + method);

            string provider, host, username, password;

            connection.MParameters.TryGetValue("provider", out provider); // Set to the name of the connector by QlikView Engine

            connection.MParameters.TryGetValue("userid", out username); // Set when creating new connection or from inside the QlikView Management Console (QMC)

            connection.MParameters.TryGetValue("password", out password); // Same as for username

            connection.MParameters.TryGetValue("host", out host); // Defined when calling createNewConnection in connectdialog.js

            switch (method)

            {

                case "getInfo":

                    response = getInfo();

                    break;

                case "getDatabases":

                    response = getDatabases(username, password);

                    break;

                case "getTables":

                    response = getTables(username, password, connection, userParameters[0], userParameters[1]);

                    break;

                case "getFields":

                    response = getFields(username, password, connection, userParameters[0], userParameters[1], userParameters[2]);

                    break;

                case "testConnection":

                    response = testConnection(userParameters[0], userParameters[1]);

                    break;

                default:

                    response = new Info { qMessage = "Unknown command" };

                    break;

            }

           return ToJson(response);    // serializes response into JSON string

        }

And another:

         public override string HandleJsonRequest(string method, string[] userParameters, QvxConnection connection)

        {

            return JsonConvert.SerializeObject(new Info {qMessage = "Test response"});

        }

Method HandleJsonRequest didn't call at all.

First implementation executes Log method, but log is empty.

Hey,

Have you solved the sendJsonRequest-problem?

If yes, can you give me an advice? I am facing a similar issue and have no idea which mistake I made that I get this error.

Thanks in advance!
