How to send mail with attachment in lambda nodeJs using SES service - email

Question

I am trying to send a mail with attachment.
I have already used SES service for sending simple and HTML content mail. but now I want to send a mail with attachments.
I am using amazon SES service for sending emails and I am using the 'sendRawEmail' method for send mail with attachments.
I am getting an error message like this.InvalidParameterValue: Nested group
I didn't find any Node examples for this type of error.

Request body:
if you want to send mail With Base64 content.
{
email: ['jen****#gmail.com', 'Aa****#gmail.com'],
from: 'no-reply#*****.com',
subject: 'Sending emails with attachments',
text: 'please find attachments',
attachments: [{
filename: 'sample.pdf',
content: {{file}}, // file content base64 staring
encoding: 'base64',
}]
}
if you want to send a mail with the file path.
{
email: ['jen****#gmail.com', 'Aa****#gmail.com'],
from: 'no-reply#*****.com',
subject: 'Sending emails with attachments',
text: 'please find attachments',
attachments: [{
filename: 'sample.pdf',
path: './home/sample,pdf'
}]
}
Business logic Code:
const ses = new AWS.SES({ region: 'us-east-1' }); //specify region for the particular see service.
const mailcomposer = require('mailcomposer');
exports.handler = function (event, context) {
console.log('Event: ',JSON.stringify(event));
if (!event.email) {
context.fail('Missing argument: email');
return;
}
if (!event.subject) {
context.fail('Missing argument: subject');
}
if (!event.from) {
context.fail('Missing argument: from');
}
if (!event.html && !event.text) {
context.fail('Missing argument: html|text');
}
const to = event.email;
const from = event.from;
const subject = event.subject;
const htmlBody = event.html;
const textBody = event.text;
const attachments = event.attachments;
const mailOptions = {
from: from,
subject: subject,
text: textBody,
html: htmlBody,
to: to,
attachments: attachments ? attachments : []
};
const mail = mailcomposer(mailOptions);
mail.build(function (err, message) {
const req = ses.sendRawEmail({ RawMessage: { Data: message } });
req.on('build', function () {
req.httpRequest.headers['Force-headers'] = '1';
});
req.send(function (err, data) {
if (err) {
console.log(err, err.stack);
context.fail('Internal Error: The email could not be sent.');
} else {
console.log(message);
console.log('The email was successfully sent')
context.succeed('The email was successfully sent');
}
});
});
};
