Node.js sendmail（）上的nodeEmailer w谷歌邮件服务帐户错误

我正在尝试从Firebase函数发送电子邮件，此时我可以获取jwt客户端、授权iy、获取令牌并创建一个NodeEmailer transporter。 但是尝试使用transporter.sendmail（）时，我得到一个错误：

      sourceUrl: 'https://accounts.google.com/o/oauth2/token',
      code: 'EAUTH',
      command: 'AUTH XOAUTH2' }

在读了很多帖子（在这么多不同的上下文中的问答）后，我迷路了。。。我的感觉是这个错误可能与refresk令牌有关。。。但谁知道呢

这是我的函数（我插入了一些console.log来观察它的进展…，所有的环境变量都设置为w functions.config（））：

jwt客户端正常吗？我想可以静坐了

代币可以吗？id_标记：未定义并刷新_标记：“jwt占位符”

此无效状态代码401的含义是什么

谢谢你的反馈。我离启动和运行它不远了，但这是经过漫长的GMail服务帐户认证后的最后一个问题

我想在你的无记名代币过期后发布它并没有什么害处，但请检查你的其他私人数据，如项目ID，不会出现在问题中。当您使用脚本/请求进行签名时，是否可以检查脚本/请求是否有效？比较gcloud和您在中创建的JWT。
