Not able to invoke the rag_chain given in the example Notebook

[testerops01]

I am trying to implement the renumics-spotlight package and I was referring to the example notebook that is given and followed the tutorial mentioned in this link.

I had to make some changes in the code in my local notebook - and the steps upto when the rag_chain is invoked works fine, but these steps fail due to Authentication error from OpenAI , which I am not able to understand why?

question = "Who built the nuerburgring"
response = rag_chain.invoke(question)
answer = response["answer"]
answer

Since the error stack trace is large, I'm sharing this via a link

Do we need to provide any additional authentication here since I've already set the env variable and also tried doing this before invoking the rag_chain

from getpass import getpass
OPENAI_API_KEY = getpass()
import os

os.environ["OPENAI_API_KEY"] = OPENAI_API_KEY

But this still makes no difference. Can you please help me out in this issue.
