const cloud = require('wx-server-sdk')
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) => {
  let access_token=event.access_token
  let job_id = event.job_id
  console.log(access_token)//token可以成功获取
  console.log(job_id)//job_id可以成功获取


  let options = {
    url: "https://api.weixin.qq.com/tcb/databasemigratequeryinfo?access_token=" + access_token,
    body: ({
      "env": "xcxdemo-20c411",
      "job_id":job_id
    })
  }
  let res = await request(options)


  return res
}

使用https://api.weixin.qq.com/tcb/databasemigrateimport?access_token=ACCESS_TOKEN这个api



将json数据导入到云开发数据后，数据已经导入到数据库中，并且返回了job_id，我想监控任务的情况，云函数内容如上图，请问错在什么地方了，报错信息如下
捕捉到的错误信息 Error: errCode: -404011 cloud function execution error | errMsg: cloud.callFunction:fail requestID ffa56083-32ed-11eb-9e5c-5254008c2339, cloud function service error code -504002, error message ReferenceError: request is not defined
