Suffering from the hell of deactivating a form

I have already read every imaginable post about this topic and I can’t know why it doesn’t work.

I thought I had solved this issue, but it gets complicated again. I’m using the classic chichats example as it is in the basic documentation.

That is to say…



  • intent x
    • form_x
    • form {“name”: “form_x”}
  • chitchat
    • respond_chitchat
    • action_ask_continue
  • deny
    • utter_stop
    • action_deactivate_form
    • form {“name”: null}

intent x comes from a mapping declared in domain.yml

when the user types something corresponding to the chitchat said intent is detected with confidence = 0.99

but then in all cases the FormPolicy returns that a form is active and the chosen action is always the form again.

My config is the following:

language: is pipeline:

  • name: WhitespaceTokenizer case_sensitive: false
  • name: LexicalSyntacticFeaturizer
  • name: CountVectorsFeaturizer analyzer: “char_wb” min_ngram: 1 max_ngram: 4
  • name: DIETClassifier batch_size: [64,128] epochs: 50

  • name: MemoizationPolicy max_history: 5

  • name: TEDPolicy max_history: 5 epochs: 40 state_featurizer: LabelTokenizerSingleStateFeaturizer

  • name: MappingPolicy

  • name: “FormPolicy”

  • name: “TwoStageFallbackPolicy” nlu_threshold: 0.5 ambiguity_threshold: 0.1 core_threshold: 0.5 fallback_core_action_name: “custom_default_fallback” fallback_nlu_action_name: “custom_default_fallback” deny_suggestion_intent_name: “deny_suggestion”

What is wrong or what should I change?
