I keep getting this issue

 api_key = self.config.api_key or os.environ["OPENAI_API_KEY"]
                                     ~~~~~~~~~~^^^^^^^^^^^^^^^^^^
  File "<frozen os>", line 714, in __getitem__
KeyError: 'OPENAI_API_KEY

By default CREWAI asks for OPEN_AI key. I want to use Ollama or chatgroq. I have tried both but it didnt work.Am I missing something here. I did exactly the same as mentioned in the documentation
