Issue with Azure OpenAI Model in HackerNews Team Example

[PankajDeck]

I have used the Azure OpenAI model as follows in cookbook/teams/01_hn_team.py example:

from phi.model.azure import AzureOpenAIChat

azure_model = AzureOpenAIChat(
    id="gpt4o",
    api_version="2024-08-01-preview",
    azure_endpoint="https://xxx-eus.openai.azure.com/",
    api_key="azure api key",
    azure_deployment="gpt-4o"
)

I then pass azure_model as a model parameter in each Agent.

Problem:
The provided example in HackerNews Team (cookbook/teams/01_hn_team.py) does not work with the Azure OpenAI model, and I receive the following error:

Error code: 400 - {'error': {'message': "'messages' must contain the word 'json' in some form, to use 'response_format' of type 'json_object'.", 'type': 'invalid_request_error', 'param': 'messages', 'code': None}}

• Does the Azure OpenAI model require a different format for messages to support response_format='json_object'?
• Are there any known workarounds or modifications needed to make this example work with Azure OpenAI?

Would appreciate any insights or fixes! Thanks in advance.

Hello @PankajDeck ! You will need to use separate instances of AzureOpenAIChat with each Agent.

This issue arrises as for hn_team, we are providing a response_model but not for the other Agents.
