未捕获的TypeError：无法读取未定义数据表的属性“长度”

Question

我想实现数据表，但我收到以下错误：

jquery.dataTables.min.js:48 Uncaught TypeError: Cannot read property 'length' of undefined
at jquery.dataTables.min.js:48
at i (jquery.dataTables.min.js:35)
at Object.success (jquery.dataTables.min.js:35)
at u (jquery-3.3.1.min.js:2)
at Object.fireWith [as resolveWith] (jquery-3.3.1.min.js:2)
at k (jquery-3.3.1.min.js:2)
at XMLHttpRequest.<anonymous> (jquery-3.3.1.min.js:2)

我的实现看起来像这样：

var oTable2 = $('#MyDataTable2').show().DataTable({
  "ajax": {
      "url": 'http://mvc/ComplaintHandlerSquadFind',                         
      "type": "GET",
      "dataSrc": "Members",
      "data": { Code : $('#input_1').val() }
  },
  "columns": [
      {"data": "Code"},
      { "data": "Name" },
      { "data": "Email" }
          ]
})

这是加载到数据表中的JSON：

[{"Members":[{"Code":"001","Name":"Bay","Email":"d1@d.com"},{"Code":"00458","Name":"Beng","Email":"d2@d.com"}]}]
