A 503 Service Unavailable Error is an HTTP response status code indicating that a server is temporarily unable to handle the request. This may be due to the server being overloaded or down for maintenance. This particular response code differs from a code like the 500 Internal Server Error we explored some time ago

Google Chrome is one of the best browsers (not for security) And is most used by
over 1 billion people around the world. Google chrome has tons of features
like Extenstions and Google currents(formerly known as google+).
Im not saying that you should use Google Chrome as your main browser
because browsers like FireFox and Edge are good alternatives for
security.

// When working with iframes, you can create a frame locator that will enter the iframe and allow locating elements in that iframe:
const locator = page.frameLocator('iframe').getByText('Submit');
await locator.click();
