Javascript 将函数部署到firestore时出错：

每次有新用户添加到我的firestore数据库时，我都会尝试触发一封电子邮件。以下代码是根据Youtube教程编写的，因为我不太熟悉部署函数。下面的代码是在functions/index.js中编写的，但是触发了一个错误，我不知道如何修复：“部署错误”。加载用户代码时函数失败。错误消息：错误：请检查函数日志以查看错误原因：。完整错误可在代码下方找到。 谢谢

我在依赖项中添加了“nodemailer”：“^6.4.11”，它现在对我有效了

您是否按照错误消息的建议查看了日志？我不确定如何记录错误。这个链接只指向文档的新页面嗨，我通过在packages.json文件中添加一些东西来解决这个问题。你节省了我的时间

const functions = require("firebase-functions");

const nodemailer = require("nodemailer");

const admin = require("firebase-admin");

admin.initializeApp();

require("dotenv").config();

const { SENDER_EMAIL, SENDER_PASSWORD } = process.env;

exports.sendEmailNotification = functions.firestore
  .document("submissions/{docId}")
  .onCreate((snap, ctx) => {
    const data = snap.data();

    let authData = nodemailer.createTransport({
      host: "smtp.gmail.com",
      port: 465,
      secure: true,
      auth: { user: SENDER_EMAIL, pass: SENDER_PASSWORD },
    });

    authData
      .sendMail({
        from: "developer@chutoro.app",
        to: `${data.email}`,
        subject: `Submssion Accepted`,
        text: `${data.email}`,
      })
      .then((res) => console.log("Successfully sent mail"))
      .catch((err) => console.log(err));
  });
