[Python] Can't Submit Captcha While automating using python, playwright and 2captch

im working on project which automates the suno.com which includes signup/login, entering prompt and generating song, but as soons as i click on generate/create button it shows me captcha. so to solve that captcha im using 2captcha, once i recieve token from 2captcha i insert it into iframe data-hcaptcha-response, i tried inserting it into text area h-captcha-response, script successfully inserts the token but im not able to submit the captcha as it's skip captcha button remains as it is, it doesnt change to verify or submit.

these are image captcha which tells to identify same images as shown in, or find images with square inside triangle like that.

here is the solve captcha function which handles captcha in my code:

async def solve_hcaptcha(page, url, site_key):
"""
Solve hCaptcha using 2Captcha and inject the response into the iframe
"""
try:
print("Starting hCaptcha solving process...")
print(f"Using site key: {site_key}")
print(f"Page URL: {url}")

# Check if hCaptcha iframe is present
hcaptcha_frame = await page.query_selector('iframe[data-hcaptcha-widget-id]')
if hcaptcha_frame:
print("✓ hCaptcha iframe detected on the page")
frame_src = await hcaptcha_frame.get_attribute('src')
print(f"Frame source: {frame_src}")
else:
print("⚠ No hCaptcha iframe found on the page")
return False

# Initialize 2Captcha solver
print("Initializing 2Captcha solver...")
solver = TwoCaptcha("api_key")
print("✓ 2Captcha solver initialized")

try:
print("Sending solve request to 2Captcha API...")
result = solver.hcaptcha(
sitekey=site_key,
url=url
)
print("✓ Received response from 2Captcha API")

token = result.get('code')
if not token:
print("⚠ Failed to solve hCaptcha: No token received")
return False

print("✓ Successfully received captcha token")
print(f"Token (first 30 chars): {token[:30]}...")

# Updated token injection approach targeting the iframe
inject_script = f"""
(() => {{
const iframe = document.querySelector('iframe[data-hcaptcha-widget-id]');
if (iframe) {{
iframe.setAttribute('data-hcaptcha-response', '{token}');

// Create and dispatch a custom event to notify any listeners
const event = new CustomEvent('hcaptcha-response', {{
detail: {{ response: '{token}' }},
bubbles: true
}});
iframe.dispatchEvent(event);

return true;
}}
return false;
}})()
"""

injection_result = await page.evaluate(inject_script)
print(f"✓ Token injection result: {injection_result}")

# Wait for any potential processing
await page.wait_for_timeout(2000)

# Try to find and click verify button if present
verify_button_selectors = [
'iframe[data-hcaptcha-widget-id]', # Try clicking the iframe itself first
'div.button-submit.button[role="button"][title="Verify Answers"]',
'.h-captcha-submit-button',
'button[type="submit"]',
'[id^="anchor-"]'
]

for selector in verify_button_selectors:
try:
button = page.locator(selector)
if await button.count() > 0:
print(f"✓ Found verify button with selector: {selector}")
await button.first.click()
print("✓ Clicked verify button")
await page.wait_for_timeout(2000)
break
except Exception as e:

print("hCaptcha solving process completed")
return True

except Exception as e:
print(f"⚠ Error during captcha solving: {str(e)}")
return False

except Exception as e:

return False


async def handle_cloudflare_verification(page):
try:
# First check if hCaptcha iframe exists
hcaptcha_frame = await page.query_selector('iframe[src*="hcaptcha"]')
if not hcaptcha_frame:
print("No hCaptcha detected on the page")
return

# Extract site key from the iframe src
frame_src = await hcaptcha_frame.get_attribute('src')
site_key_match = re.search(r'sitekey=([^&]+)', frame_src)

if site_key_match:
site_key = site_key_match.group(1)
print(f"Found site key: {site_key}")
