简要描述

我在使用微信V3支付后，服务器微信支付回调方法中 wxPayService.parsePartnerOrderNotifyV3Result一直包null，并且观看源码时发现报错地方在方法结尾的}行。

模块版本情况

• WxJava 模块名: weixin-java-pay
• WxJava 版本号: 4.5.3.B

详细描述

使用 WxPayService.createOrderV3()进行下单付款，然后在支付回调时使用wxPayService.parsePartnerOrderNotifyV3Result()来进行解析微信传过来的参数，但是一直在parsePartnerOrderNotifyV3Result()方法里报null。传过来的参数进行打印观看了，参数接受正常无错误。
parsePartnerOrderNotifyV3Result(String var1，, SignatureHeader var2) 的两个参数
var1：是 PayNotifyForm中resource下的ciphertext
