Run the code below.

from playwright.async_api import async_playwright
import asyncio
from bedrock_agentcore.tools.browser_client import BrowserClient

# Create a browser client
client = BrowserClient(region="us-east-1")

# Start a browser session
client.start()
print(f"Session ID: {client.session_id}")

url, headers = client.generate_ws_headers()


print(url)
print(headers)

async def automate_browser():
    async with async_playwright() as p:
        # Pass the generated headers for authentication, using the correct 'url'
        browser = await p.chromium.connect_over_cdp(url, headers=headers)
        page = (browser.contexts[0] if browser.contexts else await browser.new_context()).new_page()
        await page.goto("https://www.amazon.com")
        # await page.fill("input#twotabsearchtextbox", "laptop")
        # await page.press("input#twotabsearchtextbox", "Enter")
        # await page.wait_for_selector("div.s-main-slot", timeout=10000)
        # await page.screenshot(path="amazon_search.png")
        print("✅ Search complete, screenshot saved.")

await automate_browser()

@sundargthb can you take a look at this issue? I tried multiple times, none of the websocket url worked.
