Amazon web services AWS SES-nodeEmailer-transporter.sendmail不是一个函数

我有下面的代码，它给出了一个错误，说“transporter.Email”不是一个函数。我在我的package.json中指定了以下依赖项（一些内容被剥离，但它是有效的json）

乍一看，它不像是权限问题，所以排除了这一点。任何修复它的指针都会大有帮助

我在lambda中使用Node.js 8.10

应该是

transporter.sendMail

const nodemailer = require('nodemailer');
const aws = require('aws-sdk');
aws.config.update({region: 'myRegion');
const senderEmail = process.env.SENDER_EMAIL;
const destinationEmail = process.env.DESTINATION_EMAIL;
const transporter = nodemailer.createTransport({
SES: new aws.SES({
apiVersion: '2010-12-01'
})
});
exports.handler = async (event) => {
 let request = event.body;
 try {
 await this.sendEmail(request);
   return {
  'statusCode': 201,
  'headers': {
    'Access-Control-Allow-Origin': '*'
   }
 };
 } catch (error) {
return {
  'statusCode': 500
 };
  }
  };

exports.sendEmail = async (request) => {
try {
await transporter.sendEmail({
  from: senderEmail,
  to: destinationEmail,
  subject: 'Hello',
  text: 'Hello using SES'
  });
  } catch (error) {
   console.log(error);
   throw error;
   }
   };
