I'm trying to use Pupppeteer in Electron to do some automation. I tested the following code with simple command node test.js without any errors:

(async () => {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto('https://www.facebook.com/');
    await page.waitFor(2000);
    await page.click('button[type="submit"]');
    await page.waitFor(2000);
    await page.screenshot({ path: 'example.png' });
    await browser.close();
  })();

but when I ran the exact same code in in Electron I get the following error which points out there an error with await page.click('button[type="submit"]');

how can I fix it??

Try to pass a string to evaluate rather than a function (wrap it with backticks).

You can also try and wrap it with eval('your-code-as-string');
