Error message when a client wants to submit an order

[kaena]

Hello
 
I care when a client wants to validate one control in the third step, an error message is displayed:
Fatal error: Call to undefined method Product :: getAvailableDate () in / homez.743/transferf/www/modules/dateofdelivery/dateofdelivery.php on line 139
 
Do you have any idea of this problem?
I do not necessarily have any control.
 
Thank you for your help

here is the line 139:

$available_date = Product::getAvailableDate($product['id_product'], ($product['id_product_attribute'] ? (int)$product['id_product_attribute'] : null), (int)$this->context->shop->id);

 

thank you
