Hi guys,

var AWS = require("aws-sdk");
var ses = new AWS.SES();
var {getTemplate} = require("./email-template.js")

var response = {
  isBase64Encoded: false,
  headers: {
    "Content-Type": "application/json",
    "Access-Control-Allow-Origin": "*",
  },
  statusCode: 200,
  body: JSON.stringify({ success: true, message: "Email sent successfully!" }),
};

const responseFailed = (error) => ({
  isBase64Encoded: false,
  headers: {
    "Content-Type": "application/json",
    "Access-Control-Allow-Origin": "*",
  },
  statusCode: 200,
  body: `{"result": { "success": false , "error": ${error}}}`,
});


exports.handler = function (event, context) {
  console.log("Received event:", event);

  var data = event.body ? JSON.parse(event.body) : event;
  
  sendEmail(data, function (err, data) {
    console.log("error", err);
    if (err) {
       console.log("Error sending email:", err);
       return responseFailed;
    } else {
       console.log("Email sent successfully:", data);
    }

    context.done(err, null);
  });
  
  console.log("send finished");
  return response;
};
 
 
function sendEmail(event, done) {
  var senderEmail = event.senderEmail;
  var company = event.company";
  var email = event.email;
  var name = event.name;
  var message = event.message;

  var receiverEmail = event.companyEmail;
  
  var template = getTemplate({ name, email, body: message });


  var params = {
    Destination: {
      ToAddresses: [receiverEmail],
    },
    Message: {
      Body: {
        Html: {
