Hello,

await client.get_collection("collection_name")

Fails with:

qdrant_client.http.exceptions.ResponseHandlingException: Event loop is closed

Other methods, that I am using, like search, collection_exists, etc. works.

It fails even in fresh terminal sessions wrapped into asyncio.run.

It fails only on production! on my local PC with same config that comand works.
There is no difference in setup.

Thanks for help

Also:
this code from AsyncQdrantFastembedMixin add method.:

hides real issue,
I found that get_collection fails by digging into sentry log:

that happen because qdrant client tries to create collection no matter what, and hides exception from rise.

Start with the reported asyncio.run call to reproduce get_collection, then read async_qdrant_client.py around get_collection and the AsyncQdrantFastembedMixin add method. Compare the get_collection failure with the working search and collection_exists calls, and trace the ResponseHandlingException through http/api_client.py. Done means the production-only failure is reproducible and the underlying exception is no longer hidden by the add path.
