node.js - NodeJs 类型错误 : Cannot read property 'key' of undefined

Question

我想创建一个云函数，如果某些数据添加到我的数据库中，它会发送电子邮件。不幸的是，在尝试部署我的函数时，我收到此错误: 类型错误:无法读取未定义的属性“key”

这是我的功能:

const functions = require('firebase-functions')
const nodemailer = require('nodemailer')
const postmarkTransport = require('nodemailer-postmark-transport')
const admin = require('firebase-admin')

// 2. Admin SDK can only be initialized once
try {admin.initializeApp(functions.config().firebase)} catch(e) {
    console.log('dbCompaniesOnUpdate initializeApp failure')
 }

// 3. Google Cloud environment variable used:

const postmarkKey = functions.config().postmark.key
const mailTransport = nodemailer.createTransport(postmarkTransport({
auth: {
         apiKey: postmarkKey
}
  }))


 // // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase- 
 functions
//

exports.sendingEmailForlocationsRequests = 
 functions.database.ref('/clubs/{clubId}/{pushId}')
.onWrite((event) => {
//I want to retrieve the pushID        


return sendEmail();
})

    function sendEmail() {
    // 5. Send welcome email to new users
    const mailOptions = {
            from: '"Dave" <<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7b1514091e0b17023b18171a0f1e551f1e" rel="noreferrer noopener nofollow">[email protected]</a>>',
            to: '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6e02010d0f1a0701001d2e0d020f1a0b400a0b" rel="noreferrer noopener nofollow">[email protected]</a>',
            subject: 'Welcome!',
            html: `<Test>`
    }
    // 6. Process the sending of this email via nodemailer
    return mailTransport.sendMail(mailOptions)
            .then(() => console.log('dbCompaniesOnUpdate:Welcome 
    confirmation email'))
            .catch((error) => console.error('There was an error while 
    sending the email:', error))
    }

您的 Firebase 配置中似乎未设置“邮戳”。您可以使用 CLI 设置functions.config() 检索的内容:https://firebase.google.com/docs/functions/config-env
