Could you print out on what chunk is? Do you have the output logs from Llama Stack server if you are starting up your Llama Stack distribution?

I am getting similar error. Here's what print(chunk) prints:
ChatCompletionResponse(completion_message=None, logprobs=None, error={'message': '500: Internal server error: An unexpected error occurred.'})

On the server side, i see this error:
INFO: ::1:45792 - "POST /inference/chat_completion HTTP/1.1" 200 OK
