ORDER CONFIRMATION No template found for module

[besttechies]

Hi, 

On my endeavor to figure out how to build a payment method module properly for prestashop, and finally feels like I'm close to reach the finish line, but have yet again another hurdle to solve.

If anyone can be so kind, what's the problem with this situation. The payment is processed successfully, and  the customer is redirected back to the site. 

I then redirect the customer to order-confirmation, like this

 

        $success_url = $link->getPageLink('order-confirmation', null, null, array(
            'id_cart' => Tools::getValue('id_cart'),
            'id_module' => Tools::getValue('id_module'),
            'key' => Tools::getValue('key'),
        ));

But then I just see:

ORDER CONFIRMATION

No template found for module ___________

Now, what is the final piece on the puzzle that I'm missing?
