THEN Ensure proper event loop management by using asyncio.run() for async operations, or revert to synchronous opensearch-py client. Applying nest_asyncio can be a temporary workaround, but a proper async setup is recommended.

import asyncio
from opensearchpy import AsyncOpenSearch

async def check_opensearch():
    os_client = AsyncOpenSearch('localhost:9200')
    await os_client.info()
    await os_client.close()

asyncio.run(check_opensearch())
