Bug Report

Description

Hello,
I noticed that the newly added src/lib/apis/streaming
/index.ts script in version v0.1.121 fails to handle responses where the 'choices' field lacks a 'delta', with these responses coming from Azure OpenAI.

The first response from completions:

data: {"choices":[],"created":0,"id":"","model":"","object":"","prompt_filter_results":[{"prompt_index":0,"content_filter_results":{"hate":{"filtered":false,"severity":"safe"},"self_harm":{"filtered":false,"severity":"safe"},"sexual":{"filtered":false,"severity":"safe"},"violence":{"filtered":false,"severity":"safe"}}}]}

Thank you and looking forward to your response.
