AWS Lambda Nodejs 12.x using Selenium: Chrome Driver not found - node.js

Question

When I run my nodejs 12.x code calling selenium, I am getting the error below.
At the top level of my directory structure, I have my index.js file, a lib folder and a node_modules folder.
I am preparing the code on a Mac and then zipping it, uploading to S3 and running it in Lambda.
Where should my chrome and chromedriver executables be? I don't think I can use npm to install them as I think I need the linux versions for running in Lambda?
This is the error I am getting:
{
"errorType": "Error",
"errorMessage": "The ChromeDriver could not be found on the current PATH. Please download the latest version of the ChromeDriver from http://chromedriver.storage.googleapis.com/index.html and ensure it can be found on your PATH.",
"trace": [
"Error: The ChromeDriver could not be found on the current PATH. Please download the latest version of the ChromeDriver from http://chromedriver.storage.googleapis.com/index.html and ensure it can be found on your PATH.",

" at Runtime.exports.handler (/var/task/index.js:38:26)",
" at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"
]
}
This is my code
'use strict';
exports.handler = async (event, context, callback) => {
var webdriver = require('selenium-webdriver');
var chrome = require('selenium-webdriver/chrome');
var builder = new webdriver.Builder().forBrowser('chrome');
var chromeOptions = new chrome.Options();
const defaultChromeFlags = [
'--headless',
'--disable-gpu',
'--window-size=1280x1696', // Letter size
'--no-sandbox',
'--user-data-dir=/tmp/user-data',
'--hide-scrollbars',
'--enable-logging',
'--log-level=0',
'--v=99',
'--single-process',
'--data-path=/tmp/data-path',
'--ignore-certificate-errors',
'--homedir=/tmp',
'--disk-cache-dir=/tmp/cache-dir'
];
chromeOptions.setChromeBinaryPath("/var/task/lib/chrome");
chromeOptions.addArguments(defaultChromeFlags);
builder.setChromeOptions(chromeOptions);
//*****this is the problem line****//
var driver = builder.build();
driver.get(event.url);
driver.getTitle().then(function(title) {
console.log("Page title for " + event.url + " is " + title)
callback(null, 'Page title for ' + event.url + ' is ' + title);
});
driver.quit();
};

Check this:

Welcome to the lambda-selenium project! The purpose of this project is to show how to use Selenium Webdriver with Amazon Web Services (AWS) Lambda compute service.
or

Lambdium uses Selenium Webdriver with Headless Chromium to run Webdriver scripts written in JavaScript on AWS Lambda.

You can use chrome-aws-lambda package for running it headless in your lambda function , As per Documentation 512 MB of ram will be used https://www.npmjs.com/package/chrome-aws-lambda
