I'm trying to integrate gpt 4 azure open ai with Langchain but when i try to use it inside ConversationalRetrievalChain it is throwing some error
raise error.InvalidRequestError(\\n *~*
openai.error.InvalidRequestError: Must provide an \'engine\' or
\'deployment_id\' parameter to create a <class
\'openai.api_resources.chat_completion.ChatCompletion\
but if i run standalone openai instance with azure openai config it is working, I'm confused whether langchain supports gpt 4 or am I missing anything
