TypeError: Cannot read property 'qMatrix' of undefined

[#1]

I am a new user on Qlik Sense Desktop version. To familiarize with the mashup, i create a mashup using

HelpDesk Management App as base. I create  a List and added the list into the mashup.

I have confirmed the app.createList function is there and i have edited the empty callback function to :

//callbacks -- inserted here --

  function cbYear(reply, app){

      $("#divYear").empty();

    var qobject = reply.qListObject;

    console.log(qobject);  // <<===== I log this in console.

    $.each(qobject.qDataPages[0].qMatrix, function() {

        var item = this[0];

    var selT= "";

    console.log(item.qState);

    if (item.qState=="S") {

      selT=" style=\"backgroundcolor:black\"";

    }

        $("#divYear").append("<button type=checkbox " + selT + " class=\"btn btn-primary pull-right\">" + item.qText + "</button>")

      }) ;

  $("#divYear button").click( function() {

     app.field('Year').selectMatch($(this).text(),false);

  });

}

Strange thing is that the reply parameter returns no values of dimension "Year".

1. Object {qSize: Object, qDimensionInfo: Object, qExpressions: Array(0), qDataPages: Array(0)}
   1. qDataPages:Array(0)
      1. length:0 <==== nothing gets return
      2. __proto__:Array(0)
   2. qDimensionInfo:Object
      1. qApprMaxGlyphCount:0
      2. qAttrDimInfo:Array(0)
      3. qAttrExprInfo:Array(0)

And there is error in the browser console :

TypeError: Cannot read property 'qMatrix' of undefined  <====== ERROR

    at cbYear (HelpDeskMashup.js:111)

    at a (qlik.js:84)

    at qlik.js:84

    at g (require.js:45)

    at require.js:45

I search through google , but don't find anything useful on this.

Anyone can help here ?

It's too late to answer it but instead of jquery functions you should use qlik inbuilt functions (i used it in extesion),

app.getObject(objectId).then(function(e){

     // this block contains layout.qHyperCube 
     e.getHyperCubeData('/qHyperCubeDef', [{ 
          qTop: 0,  
          qLeft: 0,  
          qWidth: 10,  
          qHeight: 1000 
     }]).then(function(e){
           //this block contains Array of qDataPages.
           // perform process on data by accessing e[0].qMatrix[row][col]...
     }

})
