Error: socket hang up - Lambda nodejs function http post request - node.js

Question

I have a very simple function in Lambda using Nodejs.
The purpose of that function is to triggered a third party api every 1 minute.
So for that I have setup Cloud Watch Cron based event.
But that Api is throwing this error:
START RequestId: 54d90c9d-0a5b-4e5e-a26a-857d9bb6dd4e Version: $LATEST

It works fine in a simple nodejs code on my local machine.
Here is my Lambda Function code:
const https = require('https');
exports.handler = async (event) => {
var postData = JSON.stringify({
"client_id": "abnbfye9-qtfnf1cj-abhrhzfyf7-m2tup-6x9kk2kc5688",
"client_secret": "fpghfh329-polk80s-ye043465p1yy-45hxnfd874z06",
"inTime": new Date(),
"outTime": new Date()
});
var options = {
hostname: 'example.com',
path: '/api/updateDataLambda',
method: 'POST',
port: 443, // 👈️ replace with 80 for HTTP requests
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJfaWQiOiJ0ekpFTlNxcDJXeXh4YlNGbSIsImFjY2Vzc1Rva2VuRXhwIjp7ImRhdGUiOiIyMDIyLTA5LTI4IiwidGltZSI6IjA2OjIwOjQ1IiwidGltZVN0YW1wIjoxNjY0MzQ2MDQ1NjQ2LCJnbXQiOiIrMDAwMCJ9LCJyZWZyZXNoVG9rZW5FeHAiOnsiZGF0ZSI6IjIwMjItMDktMjgiLCJ0aW1lIjoiMDY6MjA6NDUiLCJ0aW1lU3RhbXAiOjE2NjQzNDYwNDU2NDYsImdtdCI6IiswMDAwIn0sImlhdCI6MTY2MTc1NDA0NSwiZXhwIjoxNjYxNzU0MTA1fQ.g1e5S15Q1qxB5_s4j3LFfFf6spU8gwgBUyVNLVuWNWk'
}
};
var req = https.request(options, (res) => {
console.log('statusCode:', res.statusCode);
console.log('headers:', res.headers);
res.on('data', (d) => {
process.stdout.write(d);
});
});
req.on('error', (e) => {
console.error(e);
});
req.write(postData);
req.end();
const response = {
statusCode: 200,
body: JSON.stringify('Hello from Lambda!'),
};
return response;
};
Am I doing something wrong here?
