Hi all, I’m trying to handle chitchat messages in my bot. i.e, if the user say let us say “jnndnj”, I want my nlu model to recognize it as a chitchat and to execute a fall back action. To achieve this, my first try has been to use a TwoStageFallback action, that triggered a certain actions by default. Here is my config file.
# - name: MemoizationPolicy # - name: EmbeddingPolicy - name: KerasPolicy - name: FormPolicy - name: TwoStageFallbackPolicy nlu_threshold: 0.2 core_threshold: 0.3 fallback_nlu_action_name: action_handle_default_fallback fallback_core_action_name: action_handle_default_fallback deny_suggestion_intent_name: "chitchat"
However, anytime, the user types in a chichat kind intent, the bot doesn’t always trigger the
action_handle_default_fallback and I can see in the logs, a ```None intent`` from rasa nlu`.
So my question is how to deal with this Null/None intent ?
Thanks in advance for your responses. Your sincerely.
