DataTable Warning: table id='dataTables-example' -Requested unknown parameter for row 0, column 0

cn94

I keep getting this error and though the right number of entries is listed in the table but no data is displayed. i have the correct amount of columns as in my table and my JSON is valid. I'm using node JS as my to query my database and return the results as JSON. Also the debugger crashes every time I try to run it on my page.

AJAX

$(document).ready(function() {
    $('#dataTables-example').DataTable( {
        "serverSide": false,
         "processing": true,
         "ajax":{
         "url":"http://localhost:8888/data", 
         "dataType": "JSON",
         "dataSrc": "",
         "aLengthMenu": "25",
         
        "columns": [ 
        { "data": "Name" }, 
        { "data": "Address"}, 
        { "data": "Email" }, 
        { "data": "Phone" }, 
        { "data": "Fax"}, 
        { "data": "Job" },
        { "data": "University" },
        { "data": "City" },
        { "data": "State" },
        { "data": "Zip" },      
        { "data": "Country" },
        { "data": "Status" }
        ]
    }
    });
    });

Node JS

var mysql = require("mysql");
        var express = require('express');
        var app = express();
        
        //Create connection to the db
        var con = mysql.createConnection({
              host: "localhost",
              user: "root",
              password: "root",

        });
        
app.get('/data', function(req, res) {

        res.setHeader('Access-Control-Allow-Origin', 'http://localhost:8080');
        res.setHeader('Content-Type', 'application/json');
        //Connect to db, return an error if can't connect
        con.connect(function getData(err){
              if(!err){

                
              } else {
                console.log('Error connecting to Db');
                return;
              }       
        });

        //Query the db and output the results to the console
        con.query('SELECT * FROM Data', function(err, rows)   
            {  
                if (err){
                     console.log('error');

                }
            });

        con.end(function(err) {

Solved it, had the columns within my AJAX call.

$(document).ready(function() {
$('#dataTables-example').DataTable( {
"serverSide": false,
"processing": true,
"ajax":{
"url":"http://localhost:8888/data",
"dataType": "JSON",
"dataSrc": "",
"aLengthMenu": "25",
},
"columns": [
{ "data": "Name" },
{ "data": "Address"},
{ "data": "Email" },
{ "data": "Phone" },
{ "data": "Fax"},
{ "data": "Job" },
{ "data": "University" },
{ "data": "City" },
{ "data": "State" },
{ "data": "Zip" },
{ "data": "Country" },
{ "data": "Status" }
]

});
});

```
