I'm trying to make this run but can't cause of that message. My code is as follows:

const lighthouse = require('lighthouse');
const chromeLauncher = require('chrome-launcher');
const chromium = require('chrome-aws-lambda');

exports.handler = function (event, context, callback) {

  (async () => {
    const chrome = await chromeLauncher.launch({chromeFlags: ['--headless']});
    const options = {logLevel: 'info', output: 'html', onlyCategories: ['performance'], port: chrome.port};
    const runnerResult = await lighthouse('https://google.com', options);

    // `.lhr` is the Lighthouse Result as a JS object
    console.log('Report is done for', runnerResult.lhr.finalUrl);
    console.log('Performance score was', runnerResult.lhr.categories.performance.score * 100);

    await chrome.kill();
  })()
};

And have an env variable called CHROME_PATH which has this path assigned /opt/nodejs/node_modules/chrome-aws-lambda/chromium.br

-    const chrome = await chromeLauncher.launch({chromeFlags: ['--headless']});
+    const chrome = await chromeLauncher.launch({chromeFlags: ['--headless'], chromePath: await chromium.executablePath});
