0.4.0.dev11:

I want to save the team state when my application shutdown so I can resume the task later when my application restarted. I call team.save_state() function but it return error below. How can I stop team and do ?

Error:

File "/Users/user/.pyenv/versions/3.12.2/lib/python3.12/site-packages/autogen_agentchat/teams/_group_chat/_base_group_chat.py", line 504, in save_state
    raise RuntimeError("The team cannot be saved while it is running.")
RuntimeError: The team cannot be saved while it is running.

Can you provide a code to reproduce? Because this indicates that your team is still running run or run_stream, perhaps you have not closed the async generator returned from run_stream? i.e., returning when still in async for context.

[un-hongly]

stream = team.run_stream()
async for message in stream:
    print(message)

You meant I need to break the loop of async for before I can save state?

[ekzhu]

You need to finish the async generator before you can save the state. So don't return or break from the async for loop, loop until finishes.

You can also cancel the run if you don't want to wait for all team to stop.
