Does anybody please know, what is wrong with the very simple HTML file below?

enter image description here

I am just trying to use an array of objects as the data source for DataTables:

tests.html:

<html>
<head>
<link type="text/css" rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/redmond/jquery-ui.css">
<link type="text/css" rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/jquery.dataTables/1.9.2/css/jquery.dataTables_themeroller.css">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js"></script>
<script type="text/javascript" src="https://ajax.aspnetcdn.com/ajax/jquery.dataTables/1.9.2/jquery.dataTables.min.js"></script>
<script type="text/javascript">

var data = [
    {"Name":"UpdateBootProfile","Result":"PASS","ExecutionTime":"00:00:00","Measurement":[]},
    {"Name":"NRB Boot","Result":"PASS","ExecutionTime":"00:00:50.5000000","Measurement":[{"TestName":"TOTAL_TURN_ON_TIME","Result":"PASS","Value":"50.5","LowerLimit":"NaN","UpperLimit":"NaN","ComparisonType":"nctLOG","Units":"SECONDS"}]},
    {"Name":"NvMgrCommit","Result":"PASS","ExecutionTime":"00:00:00","Measurement":[]},
    {"Name":"SyncNvToEFS","Result":"PASS","ExecutionTime":"00:00:01.2500000","Measurement":[]}
];

$(function() {
        var testsTable = $('#tests').dataTable({
                bJQueryUI: true,
                aaData: data,
                aoColumns: [
                        { mData: 'Name' },
                        { mData: 'Result' },
                        { mData: 'ExecutionTime' }
                ]
        });
});

</script>
</head>
<body>

<table id="tests">
<thead>
<tr>
<th>Name</th>
<th>Result</th>
<th>ExecutionTime</th>
</tr>
</thead>
<tbody>
</tbody>
</table>

</body>
</html>

UPDATE: Ok, I've got the answer from the author to use a newer version of DataTables or rename mData to mDataProp

For null or undefined value error, Just add this line to attributes : ,"columnDefs": [ { "defaultContent": "-", "targets": "_all" } ]

Example :

oTable = $("#bigtable").dataTable({
  "columnDefs": [{
    "defaultContent": "-",
    "targets": "_all"
  }]
});

The alert box will not show again, any empty values will be replaced with what you specified.
