on exit event does not fire in AWS Lambda

When I run this code on AWS Lambda nothing gets logged, although when I invoke this locally using serverless (framework), it does log. Is there anything that I am missing?

exports.handler = async () => {
  process.on("exit", (code) => {
    console.log("process exit code: ", code);
  });
};

Lambda endpoints stay alive even after API responds. The actual exit happens when the container that processed the request gets disposed after 15 minutes.

There is no such event in AWS Lambda to know when the container is stopped. The "Exit" event that fired when you run your code locally it a Node.js event and it is not supported by the AWS Lambda implementation.
