CakePdf not showing any data any error

[roshanapptec]

I am using CakePdf plugin to create pdf files from Html. I've installed plugin using composer and install it in bootstrap.php. Bootstrap.php

Plugin::load('CakePdf',['bootstrap' => true]);

Configure::write('CakePdf', [ 'engine' => 'CakePdf.WkHtmlToPdf', 'margin' => [ 'bottom' => 15, 'left' => 50, 'right' => 30, 'top' => 45 ], 'orientation' => 'landscape', 'download' => true ]);
Also extension is loaded in routes.php

Router::extensions('json', 'xml', 'pdf');
RequestHandler is also enabled in AppController and I've also use it in my controller. And I've used one method which I want to convert to pdf. Code in controller.

public function generatePdf() {

$billNumber = "100004";
$bill = $this->Bills->find("all")
    ->contain(['Users', 'Customers', 'PaymentGateways'])
    ->where(['bill_number' => $billNumber]);
$billDetails = $this->Bills->BillDetails->find('all')
    ->where(['bill_id' => $billNumber]);
$this->set(compact('bill', 'billDetails', 'billNumber'));

$this->viewBuilder()->options([
    'pdfConfig' => [
        'download' => true,
        'filename' => 'Invoice.pdf'
    ]
]);

}
And also view is created where output is rendered. generate_pdf.ctp:

Banana

Boom !!!

But when I am accessing my method nothing happening in browser. Only my content is showing and no error or warning is showing

What version of Cake are you using?

In my case debug info was disabled at multiple places. When I enabled it, some parent views were missing.
