Authentication Error

[hisunnymay]

Hello,

I encountered an error when trying to run the provided code snippet.

# Define signature
signature = 'sentence -> sentiment'
classify = dspy.Predict(signature)

# Run
sentence = "it's a charming and often affecting journey."
classify(sentence=sentence).sentiment

The error message received was:

AuthenticationError: Error code: 401 - {'error': {'message': 'Missing Authentication header or invalid API key', 'code': 401}}

I have verified that the API key used is correct, as it was successfully employed for calling the chat completions API. However, it is unclear where the authentication header is set. The error message indicates a potential issue with a missing Authentication header.

Thank you for your attention to this matter. If you require further clarification, please do not hesitate to let me know.
