Solving ERROR_CAPTCHA_UNSOLVABLE while using 2captcha API with Selenium for a Google reCAPTCHA: What am I doing wrong?

Question

I am getting the error ERROR_CAPTCHA_UNSOLVABLE while using the 2captcha API service to solve a google recaptcha. When I manually solve this captcha I have to click the check box and then select the images and then click on verify button. Here is how I am trying to solve this captcha and I am using selenium to get elements.

WebDriverWait(driver,23).until(EC.presence_of_all_elements_located((By.XPATH,'//div[@class="g-recaptcha"]')))
google_recaptcha = driver.find_element(By.XPATH,'//div[@class="g-recaptcha"]').get_attribute('data-sitekey')
print("SOLVING CAPTCHA")
print(google_recaptcha)
result = solve(google_recaptcha,url)
result = result['code']
WebDriverWait(driver,10).until(EC.presence_of_all_elements_located((By.ID,'g-recaptcha-response')))
driver.execute_script("document.getElementById('g-recaptcha-response').innerHTML = "+"'"+result+"'")

and here is my solve function

def solve(siteKey,url):
    sys.path.append(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))

    api_key = os.getenv('APIKEY_2CAPTCHA', 'adsasd')
    solver = TwoCaptcha(api_key)

    try:
        result = solver.recaptcha(
            sitekey=siteKey,
            url='https://2captcha.com/demo/recaptcha-v2')

    except Exception as e:
        print(e)

    else:
        return result

I am passing the current tab URL and the site key. but whenever I try this I get the exception ERROR_CAPTCHA_UNSOLVABLE. Is there any other way to solve this or I am in the wrong direction? Please guide me I am very new to this.
