Requested unknown parameter '0' for row 0 Ajax and JSON

jialero

I'm new to datatables and I'm stuck with this error: Requested unknown parameter '0' for row 0.

This is my code:

Javascript

var table = $('#myTable').DataTable({
        "bPaginate": false,
        "bInfo": false,
        "bFilter": true,
        "bProcessing" : true,
        "bServerSide": true,
        "ajax" : {
        "url" : '/guild/public/filltable',
          "type" : 'POST',
          "data": {
          "fechaInicio": $('#datepicker1').val(),
          "fechaFin" : $('#datepicker2').val(),
          "_token" :  $('input[name=_token]').val(),
          "dataSrc": "data"
        },
        "columns": [
          { "data": "code" },
          { "data": "name" },
          { "data": "price" },
          { "data": "rend" },
          { "data": "launch" },
          { "data": "risk" },
          { "data": "disp" },
          { "data": "currency" }
         ]
        },
});

HTML

<table class="ui celled table" id="myTable">
<thead>
<tr>
  <th>Code</th>
  <th>Name<th>
  <th>Price</th>
  <th>Rendto(%)</th>
  <th>Launch</th>
  <th>Risk</th>
  <th>Disp</th>
  <th>Currency</th>
</tr>
</thead>
<tbody>         
</tbody>
</table>

JSON Response

{"data":[{"code":"98174","name":"OMI IM USD Man AHL Trend","price":1.104,"rend":"-3.916","launch":"2012-05-18","risk":5,"disp":"Disp","currency":"EUR"}]}

I really don't know what to do about it, I searched many things but most of the answers were outdated. Thanks for your time.
