云函数：

const cloud = require('wx-server-sdk');
const translate = require('@vitalets/google-translate-api');
cloud.init({
  env: "wechat-online-a4c8d5",
  traceUser: true
})


// 云函数入口函数
exports.main = async (event, context) => {
  return await translate(event.translateContent, {
    from: event.from,
    to: event.to,
    tld: 'cn',
    client: 'gtx'
  });
}

客户端调用：

const data = this.getTranslatData();
    let _this = this;
    wx.cloud.callFunction({
      name: 'translate',
      data: data,
      success: res => {
        console.log('[云函数] [translate] call success: ', res.result);
        _this.setData({
          translateResult: res.result.text,
          isTranslated: true,
          isLoading: false
        })
      },
      fail: err => {
        console.error('[云函数] [translate] 调用失败', err)
        _this.setData({
          translateResult: null,
          isTranslated: false,
          isLoading: false
        })
      }
    });

关闭云函数之后调用结果：

VM125:1

请问这是啥原因导致的呢，开发者工具是最新的版本了
