警告：请求的未知参数＆＃39; 0＆＃39; 0第0行

Question

我有这个代码返回＆＃34;警告：请求的未知参数＆＃39; 0＆＃39; 0第0行和第34行;这个错误。我搜索过互联网，但无法找到解决方案。我怎么解决这个问题？

var oTable = $("#personalsTable").dataTable( {

        "processing": true,
         "serverSide": true,
        "ajax": {
        "url": "http://localhost:8081/JSON_RestFul_WebService/json/",
        "dataSrc": "personals",
        "type": "GET",
         "columns" : [
                      { "data" : "fin" },
                      { "data" : "name" },
                      { "data" : "surname"}
                     ]}     
        }); 

这是我的json，服务返回：

  "personals": [
    {
      "fin": "1",
      "name": "Ferid",
      "surname": "Qelenderli"

    {
