报错trace 麻烦提供下，不然不好确认错误原因

skuStocks传入一定要按照这个格式[{"price":10000,"quantity":100,"item_no":"XIGUA-1","skus":[{"k":"颜色","kid":1,"v":"红色","vid":1111},{"k":"产地","kid":2,"v":"福建","vid":2222},{"k":"品种","kid":3,"v":"麒麟瓜","vid":3333}]},...];price是sku价格，quantity是sku的库存，item_no是sku的商家编码，k是规格名称，kid是规格名称对应的id（开发者自定义），v是规格值名称，vid是规格值名称对应的id（开发者自定义）。要注意：sku_stocks数量=规格1数量*规格2数量*规格3数量
