How to fix lighthouse.js not supported error in Gulp?

Question

Node.js

Hello, can you tell me why I get an error when running Gulp ?

lighthouse.js

const path = require('path')
const fs = require('fs').promises
const open = require('open')
const server = require('browser-sync').create()
const del = require('del')
const lighthouse = require('lighthouse')
const chromeLauncher = require('chrome-launcher')
const { write } = require('lighthouse/lighthouse-cli/printer')
const reportGenerator = require('lighthouse/lighthouse-core/report/report-generator')

const config = require('../config')

async function getNameHTMLFiles() {
  const files = await fs.readdir(config.buildPath)

  return files.filter(item => item.endsWith('.html'))
}

function startServer() {
  return server.init({
    server: config.buildPath,
    port: config.lighthouse.PORT,
    notify: false,
    open: false,
    cors: true
  })
}

async function launchChromeAndRunLighthouse(url) {
  const chrome = await chromeLauncher.launch()
  config.lighthouse.chromeLauncherPort = chrome.port

  const result = await lighthouse(url, {
    ...config.lighthouse.flags,
    port: config.lighthouse.chromeLauncherPort
  }, config.lighthouse.config)
  await chrome.kill()

  return result
}

async function runLighthouse(fileName) {
  console.log(fileName)
  const result = await launchChromeAndRunLighthouse(`http://localhost:${config.lighthouse.PORT}/${fileName}`)

  await write(reportGenerator.generateReportHtml(result.lhr), 'html', path.join(config.lighthouse.reportPath, fileName))
}

module.exports = async function lighthouse(cb) {
  await del(config.lighthouse.reportPath)
  await fs.mkdir(config.lighthouse.reportPath)

  startServer()
  const files = await getNameHTMLFiles()

  try {
    for (const file of files) {
      await runLighthouse(file)
    }

    for (const file of files) {
      await open(path.join(config.lighthouse.reportPath, file))
    }
    cb()
    process.exit(0) //browser-sync API server.exit() do not work
  } catch (e) {
    cb(e.message)
    process.exit(1) //browser-sync API server.exit() do not work
  }
}

config.js

const path = require('path')

const root = path.join(__dirname, '../')
const src = path.join(root, 'src')

module.exports = {
  root,
  src,
  buildPath: path.join(root, '/build'),
  pug2html: {
    beautifyHtml: false
  },
  lighthouse: {
    reportPath: path.join(root, 'reports'),
    PORT: 8080,
    chromeLauncherPort: 9222,
    config: {
      extends: 'lighthouse:default'
    },
    flags: {
      // available options - https://github.com/GoogleChrome/lighthouse/#cli-options
      chromeFlags: ['--show-paint-rects'],
      output: 'html'
    }
  },
  copyDependencies: {
    dist: path.join(src, 'local_modules')
  }
}

Tell me, can someone come across?
