1.9 syntax still being used after upgrading to 1.10.x

I am using 1.10.7

I am trying to use deferRender with:

  $("#my_table").dataTable({
    ajax: $('#my_table').data('json-source'),
    deferRender: true,
    dataSrc: ""
  })

However I keep getting the error: "Uncaught TypeError: Cannot read property 'length' of undefined" from line 3315 of jquery.datatables.js, being the last line below:

// if there is an ajax source load the data
if ( dataSrc == 'ajax' ) {
  _fnBuildAjax( settings, [], function(json) {
    var aData = _fnAjaxDataSrc( settings, json );

    // Got the data - add it to the table
    for ( i=0 ; i<aData.length ; i++ ) {

when I look at the "settings" variable it lists:

bDeferLoading: false
sAjaxDataProp: "data"
sAjaxSource: null

I was surprised to see these columns and thought they would have had different values as I declared:

ajax: $('#my_table').data('json-source'),
deferRender: true,
dataSrc: ""

As the documentation for ajax.dataSrc shows, it is a child property of the ajax option. E.g. use:

$("#my_table").dataTable({
  ajax: {
    url: $('#my_table').data('json-source'),
    dataSrc: ""
  },
  deferRender: true
})

The documentation also contains other similar examples.
