I found a bug

[dorid]

I wrote a py test script. There was no problem when I requested the test interface for the first time, but after the second time, it started to report an error error: BrowserType.launch: Target page, context or browser has been closed

my code：

import asyncio

from crawl4ai import AsyncWebCrawler
from crawl4ai.async_configs import BrowserConfig
from flask import Flask, jsonify

app = Flask(name)

@app.route('/test', methods=['GET'])
def test():
async def _async_test():
# Prepare browser config with cookies
browser_config = BrowserConfig(
headers={"Accept-Language": "en-US,en;q=0.9"},
headless=False,
verbose=True
)

    web_crawler = AsyncWebCrawler(config=browser_config)
    try:
        async with web_crawler as crawler:
            await crawler.arun(url="http://google.com")
    except Exception as e:
        return {"status": f"error: {str(e)}"}
    finally:
        await web_crawler.close()
    return {"status": "test completed"}

result = asyncio.run(_async_test())
return jsonify(result)

if name == 'main':
app.run(host='0.0.0.0', port=5001)
