Assistant API how to properly handle hanging run?

[DraTeots]

I develop an app which utilizes assistant API with custom function call.

The problem I am having is that if user has two clients opened with the same thread. One of the clients create a run, which hangs in function call. Then the next client starts constantly failing at

var message = assistantClient.CreateMessage(threadInfo, MessageRole.User, new[] { MessageContent.FromText(newText) },

with

ClientResultException: HTTP 400 (invalid_request_error: )

Can't add messages to thread_4yYjTyrns5kqKcM4XZNw75wz while a run run_kdnQuv6LVnk1dzoHpTynhnFR is active.

...

And the other instance might hang forever on waiting for function call return. IDK why.

Opening the previous thread is important for the app. Thus I probably have to handle running runs somehow? There are many ways how to actually do this, but how to correctly handle it without disturbing the other running instance work?

Thank you for reaching out, @DraTeots !

What about calling the AssistantClient's GetRuns method for the AssistantThread in question and checking the Status of the latest ThreadRun? If the ThreadRun is active, you can wait and continue polling the same ThreadRun (using the AssistantClient's GetRun method) until it has reached a terminal state (i.e., IsTerminal is true) before you try calling the AssistantClient's CreateMessage method.

And the other instance might hang forever on waiting for function call return. IDK why.

By this, do you mean that the ThreadRun appears to get stuck in the RunStatus.InProgress state forever?

I will close this issue for now, but please feel free to re-open it if you still have questions. Thank you!
