Getting response from Rasa without any user input

[hknajjar0]

As soon as I open the UI in browser, the UI displays a message when it normally should do action_listen.

Here's server start:
ubuntu@ip-172-31-27-224$ docker run -p 5005:5005 -v $(pwd):/app rasa/rasa:latest-full run -p 5005 --cors "*" --enable-api --log-file out.log --debug

Then I open the UI after starting node.js server

This isn't a Rasa issue because I only see this when using Assister UI. I bolded likely culprit.

Hi @hknajjar0, thanks for reporting this issue. I guess this has to do with the way I've currently coded the listener. See predictUntilListen recursive call. My reasoning was that a chatbot/assistant will always be the one to lead the conversation, though I can see scenarios where this doesn't hold. Can you play with the linked code and tell me what works for you?

[hknajjar0]

Thanks for quick turnaround, Keyvan.
I agree in principle. However, it seems the chatbot initiates conversation in an inconsistent way.
Is there a way to hard-code it such that it always starts with utter_greet action?
