Accessing openai.ChatCompletion, no longer supported in openai>=1.0.0 - how to update the code to use the new API? (AZURE)

I'm using Azure API keys.

The error in backend logs indicates that the [openai.ChatCompletion] API has been removed in [openai>=1.0.0].

You need to update your code to use the new API.

You tried to access openai.ChatCompletion, but this is no longer supported in openai>=1.0.0 - see the README at https://github.com/openai/openai-python for the API.

You can run `openai migrate` to automatically upgrade your codebase to use the 1.0.0 interface.

Alternatively, you can pin your installation to the old version, e.g. `pip install openai==0.28`

A detailed migration guide is available here: https://github.com/openai/openai-python/discussions/742
