The Most basic Question of them All: Row 0 Column 0 error.

I am getting a row 0 column 0 error. Help.

And here is a sample of the JSON I've created:
{"draw" : 1,"recordsTotal" : 57 ,"data": [["Daisy","Gold","1366528127","","-","","-","","MD",""]]}

Here is my configuration:
$('#TableId').DataTable(
{
"columnDefs": [
{ "width": "5%", "targets": [0] },
{ "className": "text-center custom-middle-align", "targets": [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]},
],
pageLength:100,
"scrollY": "400px",
"scrollCollapse": true,

    "language":
        {
            "processing": "<div class='overlay custom-loader-background'><i class='fa fa-cog fa-spin custom-loader-color'></i></div>"
        },
    "processing": true,
    "serverSide": true,
    "ajax":
        {
            "url": "/Plugin/GetData",
            "type": "POST",
            "dataType": "JSON"
        },
    "columns": [
        { "data": "FirstName" },
        { "data": "LastName" },
        { "data": "NPI" },
        { "data": "FMFID" },
        { "data": "FMFNasalBone" },
        { "data": "NTQRID" },
        { "data": "NTQRNasalBone" },
        { "data": "MiddleName" },
        { "data": "Suffix" },
        { "data": "Comments" }
    ],
    select: true,
    buttons: [
        { extend: "create", editor: editor },
        { extend: "edit", editor: editor },
        { extend: "remove", editor: editor }
    ]
});

});
