I am trying to solve a recaptcha v2 with callback, the recaptcha is the picture solving. I’m not entirely sure what my issue is because I only get hit with the recaptcha when I am in headless mode.

I am successfully extracting the Callback and sending with the solve. When this happens, the webpage advances to the next page. But the captcha window is still open. I am struggling to click the “verify” button -I am trying various methods to switch to the iframe but the “verify” button is not found- whether I use xpath, CSS etc

Can anyone help figure out where I am going wrong with this?

def solve_recaptcha(api_key, site_key, url):
    print(f"Sending sitekey to 2Captcha: {site_key}")
    # Send the sitekey to 2Captcha for solving
    response = requests.post(
        'http://2captcha.com/in.php',
        data={
            'key': api_key,
            'method': 'userrecaptcha',
            'googlekey': site_key,
            'pageurl': url
        }
    )
    print(f"2Captcha response: {response.text}")
    if response.text.startswith('OK|'):
        captcha_id = response.text.split('|')[1]
    else:
        raise Exception(f"Error from 2Captcha: {response.text}")

    # Retrieve the CAPTCHA solution
    while True:
        time.sleep(5)
        result = requests.get(f'http://2captcha.com/res.php?key={api_key}&action=get&id={captcha_id}')
        if result.text == 'CAPCHA_NOT_READY':
            continue
        if result.text.startswith('OK|'):
            captcha_solution = result.text.split('|')[1]
            break
        else:
            raise Exception(f"Error from 2Captcha: {result.text}")

    print(f"CAPTCHA Solution: {captcha_solution}")

I attaches some pics to show how the page is advancing after submitting solve [enter image description here](https://i.sstatic.net/TpprM7PJ.png)

As you can see, the page advances after submitting the solve, but iframe containing captcha is still present

Switching to iframe with

driver.switch_to.frame(0)
wait = WebDriverWait(driver, 10)
    button = wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "[id*='verify']")))

    # Click the button
    button.click()
    print("Button clicked successfully!")
