how to import functions with aws lambda?

I am using api gateway to call a post request into my lambda which checks if the httpMethod is post, if post then do the following.

by default the entry point is index.js which I kept but then I am thinking if I am using the same lambda, I can also check if it's a get httpMethod, if so then do the following. But I want to separate my codes. Which I see for the same lambda function, I can add files. So I tried to add another file named post.js then require at index.js

Somehow, it's not passing values or calling the exported function in post.js though.

index.js

  const postHandler = require('./post.js');

  exports.handler = async (event, context) => {
      try {
          const httpm = event.context["http-method"];
          const rbody = event["body-json"];

          console.log(postHandler, 'post handler function?');  // { postHandler: [AsyncFunction] } 'post handler function?'
          console.log(httpm, 'httpmhttpm');  // 'POST'

          if (httpm === 'POST') return postHandler(rbody);
      } catch (e) {
          return e;
      }

  };

post.js // not doing anything special here, but none of these console shows up

exports.postHandler = async (rbody) => {
    console.log('I am inside postHandler()');
    console.log(rbody);

    return {status: true};
};

Thanks in advance for any suggestions / help.

// default export (change post.js file)
module.exports = async (rbody) => {
    console.log('I am inside postHandler()');
    console.log(rbody);

    return {status: true};
};

// OR !

// change (index.js file)
const { postHandler } = require('./post.js');
