注册用户时，将添加该用户，但脚本返回一个错误对象：{code："UnknownError"，消息："未知错误，来自fetch的响应正文是：未定义"}
我遵循了 https://stackoverflow.com/a/52033216/8111346 的建议。 但问题并没有解决。

在请求cognito-idp.us-west-2.amazonaws.com标头时，X-Amz-User-Agent: aws-amplify/0.1.x js被传递，但我不使用 Amplify。也许这是由于我的环境设置？
我很高兴读到你的想法。
在 cognitoUser 之前添加var解决了我的问题：
var cognitoUser = result.user;节点上没有提取。您需要使用polyfill进行获取，例如节点获取
import fetch from 'node-fetch'
global.fetch = global.fetch || fetch
但请记住，Ampify 不是为在节点上工作而设计的，因此还可能存在其他问题。
