Fabric Data Agent SDK

Hi ann33 

The `FabricOpenAI` client does not have a direct `list_messages()` method.  the correct way to list messages is to use the thread-based message listing pattern from the OpenAI Assistants API

Give this a try :

from fabric.dataagent.client import FabricOpenAI

fabric_client = FabricOpenAI(artifact_name=ai_skill_name)

response = fabric_client.beta.threads.messages.list(
thread_id=thread.id,
order="asc" 
)

print(response.model_dump_json(indent=2))

Hi ann33 ,

Thank you for reaching out to the Microsoft Fabric Community and thank you nilendraFabric for sharing the helpful response.

The warning you’re seeing is from the openai Python package, which flags that the Assistants API will eventually be replaced by the Responses API. However, it remains fully supported and will be available until at least mid-2026, with a 12-month notice before deprecation.

As of now, the Fabric Data Agent SDK supports only the Assistants API. The correct method:

fabric_client.beta.threads.messages.list(thread_id=thread.id, order="asc")

is still valid and safe to use.

If you'd prefer to remove the warning, you can suppress it using:

import warnings
warnings.filterwarnings("ignore", category=DeprecationWarning)

Support for the Responses API in Fabric will come in a future update. Meanwhile, you're good to proceed with the current SDK.

Hope this helps. Please reach out for further assistance.
