AWS SESv2: Server Error (500) - SDK

[divyasatharasi]

Created a lambda function to send email using AWS SESv2 and Node.js, it is throwing Server Error:500 error
Error with @aws-sdk/client-sesv2.
Tested on Node.js v18.12.1

`const AWS = require("@aws-sdk/client-sesv2")

const { SESv2Client, BatchGetMetricDataCommand } = AWS;

const ses = new SESv2Client({
region: "ap-south-1",
credentials: {
accessKeyId: 'xxxxx',
secretAccessKey: 'xxxxxxxxxxxx'
},
});

exports.handler = async function (event) {
var params = {
Destination: {
ToAddresses: ["recipient_email@gmail.com"],
},
Message: {
Body: {
Text: { Data: "Report" },
},

  Subject: { Data: "Test Email" },
},
Source: "source_email@gmail.com",

};

const command = new BatchGetMetricDataCommand(params);
console.log(":: command :: ", command);

async function run() {
console.log(":: run called ")
try{
const data = await ses.send(command);
console.log(' :: data :: ', data)
} catch (error) {
console.log(' :: error :: ', error)
}
}
const res = await run();
console.log(": res : ", res)
};`

Not sure if i am missing something here.
If anyone share a working sample code for sending email with attachment size of more than 10 MB using AWS SES v2, that would be helpful. Thanks in advance.
