javascript - 谷歌云功能，如何设置keyFile路径避免报错？

Question

我创建了一个使用 Gmail API 向我发送电子邮件的云功能。云功能由谷歌云调度器触发。当我在本地测试时，它似乎可以工作，但是当我将我的函数上传到谷歌云函数代码编辑器并上传时，日志中有错误。请注意，该功能似乎部署良好并且处于活动状态。

这是日志中的错误：

我不确定它指的是什么 keyFile 或如何设置它。这是我的代码：

/**
 * Triggered from a message on a Cloud Pub/Sub topic.
 *
 * @param {!Object} event Event payload.
 * @param {!Object} context Metadata for the event.
 */


 const {google} = require('googleapis');
 const {authenticate} = require('@google-cloud/local-auth');
 
 const gmail = google.gmail('v1');
 
 const sendMail = async () => {
   // Obtain user credentials to use for the request
   const auth = await authenticate(
     process.env.client_id,
     process.env.client_secret,
     [
       'https://mail.google.com/',
       'https://www.googleapis.com/auth/gmail.compose',
       'https://www.googleapis.com/auth/gmail.send',
     ],
   );
   google.options({auth});
 
   // You can use UTF-8 encoding for the subject using the method below.
   // You can also just use a plain string if you don't need anything fancy.
   const subject = ' Hello ';
   const utf8Subject = `=?utf-8?B?${Buffer.from(subject).toString('base64')}?=`;
   const messageParts = [
     'From: Oamar Kanji <[e-mail]',
     'To: Oamar Kanji <[e-mail]>',
     'Content-Type: text/html; charset=utf-8',
     'MIME-Version: 1.0',
     `Subject: ${utf8Subject}`,
     '',
     'This is a message just to say hello.',
     'So... <b>Hello!</b>  ❤️',
   ];
   const message = messageParts.join('\n');
 
   // The body needs to be base64url encoded.
   const encodedMessage = Buffer.from(message)
     .toString('base64')
     .replace(/\+/g, '-')
     .replace(/\//g, '_')
     .replace(/=+$/, '');
 
   const res = await gmail.users.messages.send({
     userId: 'me',
     requestBody: {
       raw: encodedMessage,
     },
   });
   console.log(res.data);
   return res.data;
 }
 
 exports.alertPubSub = async (event, context) => {
 
    await sendMail()

 };
