OpenAI Assistant creating new thread everytime

[yuri12344]

Bug Description

To Reproduce

1. Create send message to assistant, try use it with chat, it should works fine
2. Create a set, and input the messages and variable, as it chat return, sessionId, action: sendMessage, and chatInput
3. He will create a new thread every time you execute it manually, instead of keep in the same thread

Hey @yuri12344,

I am not fully following what the issue is here, Are you able to provide an example workflow? I would kind of expect any thread history to only be available when using the chat option or memory which it sounds like is working as expected.

It would be interesting to see what you are actually doing so we can work out if it should use an existing thread or not.

Agree. This is an issue. Same Chat should not create a new Thread in OpenAI.
By using the same thread we do not need to resend all conversation again. This is already stored in the thread.
