我正在尝试使用add.agent从uifx函数获取更新的消息变量。但是，wait函数和add.agent同时存在问题。

var message = "hi"; //test purpose
async function GetCertain_info(agent) {

  console.log("1" + message);
  await uiFx(); *//this works fine in the console.log, and it updates the message*
  console.log("2" + message);
  agent.add("Here are the information on " + message);*//this works when the await uiFx() is removed and the message variable is returned as its initial value "hi"*
}

async function uiFx() {

  var {
    ui
  } = require('./uia.js');

  return new Promise(function(resolve, reject) {

    ui().then((msg) => {
      console.log("Destination Message :  " + msg)
      message = msg;
      resolve(message);

    }).catch((msg) => {
      console.log(msg)
      message = msg;
      reject(message);
    })
  });
}

问题是什么？如何解决？
谢谢你的帮助
