// 云函数入口文件
const cloud = require('wx-server-sdk')

// 初始化 cloud
cloud.init({
  // API 调用都保持和云函数当前所在环境一致
  env: cloud.DYNAMIC_CURRENT_ENV
})

// 云函数入口函数
exports.main = async (event, context) => {
  const wxContext = cloud.getWXContext()
   
  let orderDetail = await cloud.callContainer({
    path:'/****-service/order/get/contract?id'+event.orderId,
    method: 'GET'    
  });

  return {
    event,
    openid: wxContext.OPENID,
    appid: wxContext.APPID,
    unionid: wxContext.UNIONID,
  }
}

然后云函数就报错：
