支付回调发生异常

var resHandler = new TenPayNotifyHandler(HttpContext); var orderReturnJson = await resHandler.DecryptGetObjectAsync(false); 更新到最新的版本（Senparc.Weixin.TenPayV3 2.6.1）发生异常信息，我看异常信息应该是JSON 反序列化时类型不匹配 错误位置：$.promotion_detail[0].wechatpay_contribute（JSON 中第一个优惠详情的 wechatpay_contribute 字段） 预期类型：string（字符串） 实际类型：number（数字，如 100） C# 模型中 wechatpay_contribute 属性定义为 string，但微信支付返回的 JSON 中该字段是数字（例如 0 或 100），导致反序列化失败。 需做个兼容设置或直接改成int类型（wechatpay_contribute，merchant_contribute ，other_contribute ）
