When calling two OpenAI Assistant v2 operations in async, wrong assistant_id gets used

[faratech]

I am calling an intensive operation in async using FastAPI to tag a bunch of content. When I go to run another script and utilize the same FastAPI endpoint, the JSON I get back is a response to the request I sent, but the payload/response shows the assistant_id used was the one I am calling for this other operation, even though I am explicitely sending the assistant_id to the FastAPI endpoint. When I discontinue my job running in the background the issue stops. This tells me that if I run multiple operatons in AsyncOpenAI concurrently, they will ultimately get confused running in concurrence. Does AsyncOpenAI client internally manages sessions in a way that isolates requests or will it re-use sessions across requests?
