There is a problem with categorical slots that worries me a lot. Dialog example: User: I want a chocolate bar? Bot: You can buy a chocolate bar in our store using the link: ... User: I want a white chocolate (the entity "white" is extracted and placed in the slot) Bot: You can buy a white chocolate bar in our store at the link: ... User: I want a chocolate bar? Bot: You can buy a white chocolate bar in our store at the link: ... First problem: the slot is not updated to the value “None” if the intent goes without specifying the entity. The second problem: For example, the User sealed himself up and asked “I want a wite chocolate”, then the extracted entity will be “wite” despite the fact that there is no such slot category, how to cope with this? I know that you can use synonyms, but it is impossible to take into account all the typos. nlu: - intent: i_want_a_chocolate_bar examples: | - I want a chocolate bar - want a chocolate - I want a [white](chocolate_type) chocolate - want a [white](chocolate_type) chocolate - I want a [milk](chocolate_type) chocolate - want a [milk](chocolate_type) chocolate - I want a [dark](chocolate_type) chocolate - want a [dark](chocolate_type) chocolate stories: - story: i_want_a_chocolate_bar steps: - intent: i_want_a_chocolate_bar - slot_was_set: - chocolate_type: null - action: utter_i_want_a_chocolate_bar - story: i_want_a_white_chocolate steps: - intent: i_want_a_chocolate_bar - slot_was_set: - chocolate_type: white - action: utter_i_want_a_white_chocolate - story: i_want_a_milk_chocolate steps: - intent: i_want_a_chocolate_bar - slot_was_set: - chocolate_type: milk - action: utter_i_want_a_milk_chocolate - story: i_want_a_dark_chocolate steps: - intent: i_want_a_chocolate_bar - slot_was_set: - chocolate_type: dark - action: utter_i_want_a_dark_chocolate domain: intents: - i_want_a_chocolate_bar entities: - chocolate_type slots: chocolate_type: type: categorical values: - white - milk - dark responses: utter_i_want_a_chocolate_bar: - text: "You can buy a chocolate bar in our store using the link: ..." utter_i_want_a_white_chocolate: - text: "You can buy a white chocolate bar in our store at the link: ..." utter_i_want_a_milk_chocolate: - text: "You can buy milk chocolate in our store at the link: ..." utter_i_want_a_dark_chocolate: - text: "You can buy a dark chocolate bar in our store at the link: ..." session_config: session_expiration_time: 60 carry_over_slots_to_new_session: true

Error when working with categorical slot

Welcome to the forum

Yes, that is the expected behavior.

Slots are for long-term storage. If you want short-term storage, use entities.

That’s weird indeed.

Can you share rasa --version?

Please look at this thread as well.
