• In widget preview contexts, item/item.documents[0].data may be undefined; setting itemData = item.documents[0].data unconditionally can throw and break the preview. Only read item.documents[0].data when not in preview and when it is defined, and initialize brand/model to empty strings otherwise.

• isGuaranteeLabelVisible() dereferences basketItem.variation.data.item.manufacturer.name without checking that manufacturer exists. If an item has no manufacturer, this will throw and break rendering even when the guarantee label is disabled.

            return this.isDataFieldVisible("basket.item.guaranteeLabel") &&
                !!(this.basketItem.variation.data.item.manufacturer.name && this.basketItem.variation.data.variation.model);
        },
