When does this happen?

IF OpenAI API returns HTTP 200 but throws an APIError during streaming, often due to rate_limit_usage included in response body.

How others solved it

THEN Enable LLM caching (e.g., InMemoryCache or RedisCache) in LangChain to reduce the number of API calls and mitigate intermittent errors from OpenAI's service abnormalities.

from langchain.globals import set_llm_cache
from langchain.cache import InMemoryCache
set_llm_cache(InMemoryCache())
