Hi, I have a problem with my Rasa project which I have not managed to solve and I would appreciate your help very much.
First this link is broken: https://rasa.com/docs/rasa-pro/building-assistants/handling-user-silence/
The problem: I have not managed to make the silence_timeout and session_timeout work.
in my credentials.yml file I have the following:
socketio: bot_message_evt: bot_uttered session_persistence: true user_message_evt: user_uttered
In my config.yml file I have the following:
policies:
- name: FlowPolicy silence_timeout: 45 # Time in seconds consecutive_silence_timeouts: 2 # Number of timeouts before ending flow silence_reminder_message: “You have been silent for some time, do you need more help?” silence_timeout_enabled: true session_timeout_message: “You have been silent for too long. I am closing the session.”
- name: IntentlessPolicy
session_config: session_expiration_time: 2 # in minutes carry_over_slots_to_new_session: true
in my default flows.yml file I have the following:
pattern_silence_timeout: description: Flow for handling silence timeouts when the user is silent for too long name: pattern silence timeout nlu_trigger: - intent: intent_silence_timeout steps: - action: utter_silence_reminder pattern_session_timeout: description: Flow for handling session expiration when the user has been silent for too long name: pattern session timeout nlu_trigger: - intent: intent_session_timeout steps: - action: utter_session_timeout - noop: true next: END
I am using the Rasa chat widget on the front-end. The app works fine, everything works but if I leave the web-page with the Rasa chat widget open and leave without typing anything in the chat widget (if I am idle), the silence timeout or the session timeout never kick in. Even if I am idle for hours, I never see the messages “You have been silent for some time, do you need more help?” or “You have been silent for too long. I am closing the session.” and if I run the app with the --debug flag I do not see anything happening after the time I set expires.
If a user is idle for a long time I want my Rasa app to close the WebSocket connection/session and release the server resources for that WebSocket. Because if many users are using the app and connections / sessions or server resources are not released the server will be overwhelmed.
What I am doing wrong? Can you help me?
If silence_timeout and session_timeout work only with voice channels then does a Rasa app which works only with a text chat widget (socket.io WebSockets) release server resources when a user is idle?
Thank you
