Why I am getting this error

I'm sorry, I cannot reproduce:

@elacuesta thanks for the quick reply. Yes it is working when working on project separately. but one more issue when I make

"PLAYWRIGHT_LAUNCH_OPTIONS": {
            "headless": True,
        },

the prints None not the title.
why so?

[elacuesta]

I see. I suppose the site could be detecting and blocking headless browsers, I'm seeing the same behavior with standalone Playwright:

import asyncio

from playwright.async_api import async_playwright

async def main():
    async with async_playwright() as pw:
        browser = await pw.chromium.launch(headless=False)
        page = await browser.new_page()
        await page.goto(URL)
        await page.screenshot(path="page.png")
        print(await page.locator("//h1").text_content())
        await browser.close()

if __name__ == "__main__":
    asyncio.run(main())

prints iFFALCON Q73 126 cm (50 inch) 4K Ultra HD QLED Google TV with Dolby Audio (2023 model), however by passing headless=True I get a 403 response with "Access Denied".
