session error when chat with copilot python sdk

[zeerd]

Anyone who can give me some suggest ... Thx.

github-copilot-sdk==0.2.0

I tried copilot v1.0.9/v1.0.10/v1.0.11
I tried to delete /root/.cache.

import asyncio
from copilot import CopilotClient
from copilot.types import PermissionHandler


async def main():
    # Create and start client
    client = CopilotClient()
    await client.start()

    # Create a session
    conf = {
        "model": "gpt-4.1",
        "on_permission_request": PermissionHandler.approve_all,
        "tools": []
    }
    session = await client.create_session(**conf)
    # await session.set_model("gpt-4.1")

    # Wait for response using session.idle event
    done = asyncio.Event()

    def on_event(event):
        print(f"Received event: {event.type.value}")
        print(f'Received data: {event.data}')
        if event.type.value == "assistant.message":
            print(event.data.content)
        elif event.type.value == "session.idle":
            done.set()

    session.on(on_event)

    # Send a message and wait for completion
    await session.send({
        "prompt": (
            "Who are you and what model you are "
            "and what kind of assistant you are?"
        )
    })
    await done.wait()

    # Clean up
    await session.disconnect()
    await client.stop()

asyncio.run(main())

@zeerd Some of the APIs you're using there are out-of-date. For example send now takes a prompt string directly, not as a dictionary entry.

Could you try running the Python sample at python\samples\chat.py? This works for me locally.

Consider running pip install --force-reinstall --pre github-copilot-sdk first.

Thank you! python\samples\chat.py works.

However, such backward-incompatible interface changes with this level of density are truly hard to accept.
