已经有android和iOS平台上架，使用了现有的服务端接口创建支付信息appResultInfo private async wechatPay(appResultInfo:Record<string, string>):Promise<SendReqResultWrap> { let req = new wxopensdk.PayReq req.partnerId = appResultInfo['partnerid'] req.appId = appResultInfo['appid'] req.packageValue = appResultInfo['package'] req.prepayId = appResultInfo['prepayid'] req.nonceStr = appResultInfo['noncestr'] req.timeStamp = appResultInfo['timestamp'] req.sign = appResultInfo['sign'] return await this.wxApi.sendReq(YTDAppManager.getContext(), req) } 这段代码发执行返回false，查看日志[wxopensdk::WXApi] openWechat fail by err:{"code":16000001} 请问该怎么排查问题
