When does this happen?

IF OpensearchVectorClient leaves unclosed aiohttp client sessions and connectors when destroyed, causing warnings.

How others solved it

THEN Ensure the async OpenSearch client is explicitly closed after use. In a test or application cleanup, call await client._os_async_client.close() to release connections and avoid resource leaks. Wrap usage in try...finally to guarantee cleanup.

async def use_opensearch():
    client = OpensearchVectorClient(endpoint="localhost:9200", index="test", dim=3)
    try:
        # use client
        pass
    finally:
        await client._os_async_client.close()
