Is there an existing issue for the same bug?

Describe the bug and reproduction steps

If you choose your deployed model as Azure o1 or o1-preview and run the agent with any request.

You get the following error:

litellm.BadRequestError: AzureException BadRequestError - Error code: 400 - {'error': {'message': "Unsupported value: 'messages[0].role' does not support 'system' with this model.", 'type': 'invalid_request_error', 'param': 'messages[0].role', 'code': 'unsupported_value'}}

Docker is installed on windows and container is launched from within WSL. Exact issue: https://github.com/All-Hands-AI/OpenHands/issues/4839

The other day this issue on recognizing o1 models on Azure was fixed in litellm. Once o1 is recognized, it means that litellm will apply transformations like replacement of the system prompt with a user message, so that it works normally.

I'll test their release with the fix. I'm not sure why it happens on o1-preview too, though.

@rw-MohamedAbouseif Sorry for the delay on answering. This was fixed a while ago. I will close this, but if you see it again on any model, please feel free to reopen.
