Serverless framework: Chrome "Error: spawn ETXTBSY", - node.js

Question

I'm getting started trying to write a lambda function with node and puppeteer. I'm using the serverless framework
I've been trying to follow directions at https://github.com/alixaxel/chrome-aws-lambda. My function is working as expected locally, with:
$ sls invoke local -f hello
However when I run:
$ sls invoke -f hello
I get:
{
"errorType": "Error",
"errorMessage": "spawn ETXTBSY",
"trace": [
"Error: spawn ETXTBSY",
" at ChildProcess.spawn (internal/child_process.js:407:11)",
" at Object.spawn (child_process.js:548:9)",
" at Launcher.launch (/opt/nodejs/node_modules/puppeteer-core/lib/Launcher.js:132:40)",
" at async Object.main (/var/task/index.js:50:15)",
" at async module.exports.hello (/var/task/handler.js:6:13)"
]
How can I get this working?
My handler.js contains:
'use strict';
var index = require('./index.js');
module.exports.hello = async event => {
// var t = async event => {
var res = await index.main();
console.log('hello');
console.log(res);
console.log('IN HANDLER');
return {
statusCode: 200,
body: JSON.stringify(
{
message: 'main function executed!',
input: event,
......
my index.js contains:
async function main(event, context, callback) {
const os = require('os');
let result = null;
let browser = null;
if (os.platform=='win32') {
const puppeteer= require('puppeteer-core');
browser = await puppeteer.launch({
executablePath: 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe',
headless: false,
ignoreHTTPSErrors:true
})
} else {
// launch a headless browser
const chromeLambda = require('chrome-aws-lambda');
console.log(os.platform());
console.log('lambda');
browser = await chromeLambda.puppeteer.launch({
args: chromeLambda.args,
executablePath: await chromeLambda.executablePath,
defaultViewport,
headless:true
});
var page = await browser.newPage();
........
};
module.exports.main = main;
