在云函数中(共享的云环境)使用tenpay库 调用企业付款接口进行提现，商户32位密钥已经指定，同时

pfx: require('fs').readFileSync('apiclient_cert.p12'), //证书初始化

const config = {

  appid: 'xxx', //小程序Appid

  envName: 'xxx', // 小程序云开发环境ID

  mchid: 'xxx', //商户号

  partnerKey: 'xxx', //此处填服务商密钥

  pfx: require('fs').readFileSync('apiclient_cert.p12'), //证书初始化

  actionName:'xxx',

  rate:0 

};

  let result = await pay.transfers({

        partner_trade_no: 'scorereflect' + Date.now() + num,

        openid: userInfo._openid,

        check_name: 'NO_CHECK',

        amount: parseInt(num) * (100 - config.rate),

        desc: config.actionName,

  });

每次结果都报错：

报错：Error: cloud.callFunction:fail Error: errCode: -504002 functions execute fail | errMsg: Error: mac verify failure, POST https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers -1 (connected: false, keepalive socket: false, socketHandledRequests: 0, socketHandledResponses: 0)
