Address delivery error

[AcidLava]

Hello,

I got the following error in logs "Trying to get property 'id_address_delivery' of non-object".

It refers to a VAT module :

       if ($address->id == NULL) {
            $address = new Address(
                (int)Context::getContext()->cart->id_address_delivery
            );
        }

Any idea on how I can solve this ?

Thanks !
