Chatflow calling an Internal Chatflow: How to override Session ID for Langfuse?

[dkindlund]

So I have a main chatflow that's internally calling another chatflow. Both chatflows are logging to Langfuse. Because each chatflow invocation has a unique "sessionId", Langfuse doesn't correlate the traces for this activity together in a single session.

My question is: Is it possible to take the $flow.chatId from the first chatflow and pass it into the internal second chatflow as an override? That way, when Langfuse reports the activity, it shows both chatflow invocations tied to the same session.

Let me know your thoughts here, @HenryHengZJ . Thanks!

@dkindlund not sure if this helps, but just merged a PR which outputs the chatId along with the text response. Otherwise, I'd suggest provide the chatId in the API body request, so it can override the automatically generated one

Hey @HenryHengZJ , just to confirm, so if I provide a chatId in the API body request, Flowise will automatically use that one instead of generating a new chatId when executing a chatflow?

yep:

Wow, that's awesome -- thanks so much, @HenryHengZJ!
