Basic Agent Creation - Python yields in error

[Jandev]

The sample provided on this page: https://learn.microsoft.com/en-us/agent-framework/user-guide/agents/agent-types/azure-ai-foundry-agent?pivots=programming-language-python#basic-agent-creation shows the following code:

        AzureCliCredential() as credential,
        AzureAIAgentClient(async_credential=credential).as_agent(
            name="HelperAgent",
            instructions="You are a helpful assistant."
        ) as agent,
    ):

When trying this code in my FastAPI endpoint I get an error stating:

Azure credential is required when agents_client is not provided.

I had to change my code to the following to get the code working: AzureAIAgentClient(credential=credential).as_agent(

Full sample:

class calculator:
    async def run(self, question: str):
        answer = "I don't know"
        async with AzureCliCredential() as credential:
            async with AzureAIAgentClient(credential=credential).as_agent(
                name="HelperAgent",
                instructions="You are a helpful assistant."
                ) as agent:
                answer = await agent.run(question)

        return answer

I'm not sure if the behavior is different between a console app & FastAPI endpoint (which is also marked as async, but the error is confusing at least. It looks like the code sample needs updating, but might need some more testing.
