Start by reading the connection path in /app/clientmanager/weaviate.py at line 98 and its caller in /app/api/routes.py at line 154, then check how the Weaviate client selects its HTTP transport and timeout type. Reproduce with the reported Weaviate, LangChain, and OpenAI setup; done when client.connect() succeeds without the Timeout type error.

I have both weaviate client 4.24.0 in my app as well as langchain with openai

it seems like weaviate client uses httpx while langchain and openai have httpx2 and somehow the weaviate client is attempting to make requests with httpx2 which doesn't like the Timeout object

I can't seem to find a workaround and i know that the weaviate client libraray doesn't import httpx2
