'[8] Undefined index: quantity' error

[andreiven]

So when I go to the back-end to view an order I get this error:

Notice on line 819 in file /home/b1040623/public_html/modules/dpdgeopost/models/Shipment.php

[8] Undefined index: quantity

 

 

line 819 writes this: $cart_quantity = isset($product['product_quantity']) ? $product['product_quantity'] : $product['quantity'];

 

does somebody know what's going on?

var_dump($product);

i think there is no quantity information in $product,
