When does this happen?

IF When providing a custom httpx client (sync or async) to ChatOpenAI, a type validation error occurs, especially with openai>=1.14.2.

How others solved it

THEN Update langchain-openai to version >=0.1.0 to fix the sync client issue. For async clients, ensure you pass the async client via the 'http_async_client' parameter (not 'http_client'). If using custom clients, match the expected type: httpx.Client for sync, httpx.AsyncClient for async.

from langchain_openai import ChatOpenAI
import httpx

# Sync client
http_client = httpx.Client()
llm = ChatOpenAI(model="gpt-4", openai_api_key="...", http_client=http_client)

# Async client
http_async_client = httpx.AsyncClient()
llm_async = ChatOpenAI(model="gpt-4", openai_api_key="...", http_async_client=http_async_client)
