Regardless what i tried , i'm always getting executablePath is undefined. Unfortunately there's not much info on this on google. It would be great anyone could let me know where to dig into deeper to solve this error. revisionInfo is returning undefined.

Error

BrowserFetcher {
  _product: 'chrome',
  _downloadsFolder: '/var/www/node_modules/puppeteer/.local-chromium',
  _downloadHost: 'https://storage.googleapis.com',
  _platform: 'linux' }

      headless: false,
      executablePath: revisionInfo.executablePath,
      args: ['--window-size=1920,1080', '--disable-notifications'],

    await page.goto('https://example.com', {
      waitUntil: 'networkidle0',
    });

    await page.close();
    await browser.close();
  } catch (e) {
    console.error(e);
  }
};
