I am getting frequent openai.InternalServerError: Error code: 500 - {‘code’: 0, ‘error’: ‘I/O reactor has been shut down’, ‘requestId’: ‘’} errors. I have built a web app using streamlit and am using langchain_openai AzureChatOpenAI. I am not able to figure out why exactly this is happening. The error isn’t consistent and seems to happening at random.
