[Bug]: 'page.waitForTimeout' not working in Puppeteer 22.7.1

[YAnubhavChetan]

Minimal, reproducible example

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch({ headless: "new" }); 
  const page = await browser.newPage();

  try {
    await page.goto('https://www.google.com/');
    console.log('Navigated to Google website.');

    // Wait for 2 seconds using page.waitForTimeout
    await page.waitForTimeout(2000);
    console.log('Waited for 2 seconds using page.waitForTimeout');

  } catch (error) {
    console.error('Error occurred:', error);
  } finally {
    await browser.close();
  }
})();

Error string

Error occurred: TypeError: page.waitForTimeout is not a function

Bug behavior

Background

I was trying to use waitForTimeout function in my nodejs puppeteer program, but it shows TypeError for the past two days.
I have updated my puppeteer version from 21.9.0 to 22.7.1 before running the program. I run the program several time afterwards but it gets the same TypeError.

So I downgrade my puppeteer version to 21.9.0 and run the program afterwards and this time I don't find any error, which lead me to think that its definitely a bug in this new version.

Then I created this simple puppeteer code to demonstrate the error i am encountering with the latest version.

Expectation

The code working is simple as you can see it yourself.

When run, this code goes to google website and then wait for two seconds and close it.

Reality

But it shows the TypeError on the waitForTimeout function.

This issue was not reproducible. Please check that your example runs locally and the following:

• Ensure the script does not rely on dependencies outside of puppeteer and puppeteer-core.
• Ensure the error string is just the error message.

  • Bad:

    Error: something went wrong
      at Object.<anonymous> (/Users/username/repository/script.js:2:1)
      at Module._compile (node:internal/modules/cjs/loader:1159:14)

      at node:internal/main/run_main_module:23:47

  • Good: Error: something went wrong.

• Ensure your configuration file (if applicable) is valid.
• If the issue is flaky (does not reproduce all the time), make sure 'Flaky' is checked.
• If the issue is not expected to error, make sure to write 'no error'.

Once the above checks are satisfied, please edit your issue with the changes and we will
try to reproduce the bug again.
