Issue for Communication

[lylehust]

I installed apple-to-openai successfully in my Mac mini M4, as following. Mac OS is 26.3.1.

$ uv run apple-to-openai
INFO: Started server process [40806]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)

And, also could get health and models information.
$ curl http://localhost:8000/health
{"status":"ok"}

$ curl http://localhost:8000/v1/models
{"object":"list","data":[{"id":"apple-intelligence","object":"model","created":0,"owned_by":"apple"}]}

However, I got the error message when I tried to send "What is apple intelligence" message to AI.

$ curl -N http://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{
"model": "apple-intelligence",
"messages": [{"role": "user", "content": "What is Apple Intelligence?"}],
"stream": true
}'
data: {"id": "chatcmpl-ed688aba07b1", "object": "chat.completion.chunk", "created": 1773705987, "model": "apple-intelligence", "choices": [{"index": 0, "delta": {"role": "assistant"}, "finish_reason": null}]}

data: {"error": {"message": "Apple Foundation Model error: Generation error (status: 255): None", "type": "server_error", "code": "provider_error"}}

How to fix the issue?

Thank you.
