When does this happen?

IF OpenSearch vector store becomes unstable after PR #11513, especially when used with FastAPI, producing 'This event loop is already running' or 'Timeout context manager should be used inside a task' errors.

How others solved it

THEN Revert to using the synchronous opensearch-py client (OpenSearch instead of AsyncOpenSearch) to avoid event loop conflicts. Alternatively, if async is required, wrap each async operation in asyncio.run() and manage the event loop explicitly.

from opensearchpy import OpenSearch
client = OpenSearch('localhost:9200')
# Use sync methods like client.indices.create() etc.
