old code

        return array_map(function ($item) {

            $item->weight = $item->weight ?? 0;
            $unit = $item->has_variants 
                ? (isset($item->variant_data->unit) ? $item->variant_data->unit : (isset($item->unit) ? $item->unit : null)) 
                : (isset($item->unit) ? $item->unit : null);
            $item->unit = $unit;
            $item->weight_total = bcmul($item->weight, (int) $item->cart_item->quantity, 2);
            $item->weight_total_with_unit = SettingsHelper::getWeightWithUnit($item->weight_total, $unit);
            $item->weight_with_unit = SettingsHelper::getWeightWithUnit($item->weight, $unit);
            return $item;
        }, $products);

New code

return array_map(function ($item) {

            $item->weight = $item->weight ?? 0;
            $unit = $item->has_variants 
                ? (isset($item->variant_data->unit) ? $item->variant_data->unit : (isset($item->unit) ? $item->unit : null)) 
                : (isset($item->unit) ? $item->unit : null);
            $item->unit = $unit;

            $quantity = isset($item->cart_item) && isset($item->cart_item->quantity) ? (int) $item->cart_item->quantity : 0;

            $item->weight_total = bcmul($item->weight, $quantity, 2);
            $item->weight_total_with_unit = SettingsHelper::getWeightWithUnit($item->weight_total, $unit);
            $item->weight_with_unit = SettingsHelper::getWeightWithUnit($item->weight, $unit);

            return $item;
        }, $products);
