Google Search Console -> Shopping -> Merchant Listings :

Critical error: Missing field “priceType” (in “offers.priceSpecification”)

Items with this issue are invalid. Invalid items are not eligible for Google Search’s rich results

有两个站，一个站没有报这个错误，另一个站报这个错误了，是Schema中少了一个priceType。但是两个站的设置没有发现不一样的地方，奇怪了。
