I have the simple DataTable that should be populated with data using the bellow AJAX call. Except that when the page load, I get the error message "Uncaught TypeError: undefined is not a function"

The reason why I have so many imports is because I am working with a very complex datatable.

JavaScript

<script type="text/javascript">
   var contractUrl = "Service.asmx/GetContracts";
   $(document).ready(function() {
    var table = $('#contracts').DataTable({
    dom: 'lBfrtip',
    stateSave: true,
    lengthChange: false,
        buttons: [
            'pageLength','excel'
        ],
    scrollY:        300,
    scrollX:        true,
    scrollCollapse: true,
    columnDefs: [
        { width: 200, targets: 0 }
    ],
    fixedColumns: true,
        stateSave: true,
    "processing": false,
    "serverSide": true,
    "ajax": {
        type: "POST",
        url: contractUrl,
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        },
    "columns": [ 
            { "data": "Code" }, 
            { "data": "ContractType" }],
    "lengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
    "pagingType": "full_numbers",
    "searching": false
} );

table.buttons().container()
    .appendTo( $('div.eight.column:eq(0)', table.table().container()) );
});

</script>

Here is my Json 

[{"Code":"Dev","ContractType":"GPO"}]

The only syntax error you have is defining the stateSave property twice on the config object.

I tried to initialize with your code + some dummy data i got from their examples.

I had to comment out ajax and columns properties. Also, I had to comment stateSave (both times :) ), but this might have to do with StackOverflow limitations. To be clear: having it once might not be possible on SO. Having it twice is an error and won't work anywhere.

Everything else seems fine, including the table.buttons().

Because of the duplicated property on config object DataTable() does not correctly initiate and the methods you're trying to access are not exposed.

See it working in this example: 

$(document).ready(function() {
  table = $('#contracts').DataTable({
    dom: 'lBfrtip',
    // stateSave: true,
    lengthChange: false,
    buttons: [
      'pageLength', 'excel'
    ],
    scrollY: 300,
    scrollX: true,
    scrollCollapse: true,
    columnDefs: [{
      width: 200,
      targets: 0
    }],
    fixedColumns: true,
    // stateSave: true,
    processing: false,
    // serverSide: true,
    /* "ajax": {
        type: "POST",
        url: contractUrl,
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        },
    // replaced with data, below
        */
    data: dataSet(),
    columns: [
      { title: "Name"},
      { title: "Position"},
      { title: "Office"},
      { title: "Extn."},
      { title: "Start date"},
      { title: "Salary"}
    ],
    lengthMenu: [
      [10, 25, 50, -1],
      [10, 25, 50, "All"]
    ],
    pagingType: "full_numbers",
    searching: false
  });
  table.buttons().container().appendTo($('div.eight.column:eq(0)', table.table().container()));
});
