To Reproduce
Steps to reproduce the behavior:

Getting the error that ask me to check my api key in opneAPI platform when I clearly set a non-openAPI llm model

error
openai.AuthenticationError: Error code: 401 - {'error': {'message': 'Incorrect API key provided: sk-or-v1*************************************************************c0ed.
