Seems like you forgot to provide columns option as explained in the tutorial.

[renjithjr]

No i have provided columns option as explained in the tutorial.

$columns = [ [ 'field' => 'Customers.id', 'data' => 'id', 'searchable' => false, ],
[ 'title' => ('Title'), 'field' => 'Customers.name', 'data' => 'name' ], [ 'title' => ('Actions'), 'field' => 'Customers.id', 'data' => 'id' ], ];

Please provide full code, this snippet does not show your call into DataTables helper.

[renjithjr]

### Controller

public function index() { $columns = [ [ 'field' => 'Customers.id', 'data' => 'id', 'searchable' => false, ],
[ 'title' => ('Title'), 'field' => 'Customers.name', 'data' => 'name' ], [ 'title' => ('Actions'), 'field' => 'Customers.id', 'data' => 'id' ], ];

    $data = $this->DataTables->find('Customers', 'all', ['conditions'=>[], 'order'=>'Customers.id desc'], $columns);

    $this->set('columns', $columns);
    $this->set('data', $data);
    $this->set('_serialize', array_merge($this->viewVars['_serialize'], ['data']));
}

Please format your code in a readable manner, to be honest I consider it quite rude to dump the code like this when you are asking for help.

Next time try ```php it is in the Github Markdown documentation.

There is some other problems in your code, but I really don't see how you could get to this error message with the code you posted.

1. use $columns passed from controller instead of re-defining
2. selector argument to draw() is missing a '#'
3. what's the document.ready event handler supposed to do?
