I have an issue that a form using from_intent will trigger action fallback after deactivating the form, instead of doing the action at the end of the form rule (action_start_scenario below). In debug, I would see the error There is no applicable rule. and that the fallback is activated. I was able to work around this using from_entity instead, and my guess is that the intents in my button payloads somehow messes up the action prediction after the form closes. Anyone understand why it does like this, and is it documented somewhere?
The form is:
forms:
scenario_form:
scenario:
- type: from_intent
value: apartment
intent: play_scenario
- type: from_intent
value: play_scenario
intent: pick_interview
The intention is to let the user select with buttons, and so I assumed that the best mapping would be from_intent with a unique intent for each button. So I have an utterance like this:
utter_ask_scenario_form_scenario:
- text: Pick a scenario
buttons:
- title: Apartment
payload: /pick_apartment
- title: Interview
payload: /pick_interview
And a rule like this:
- rule: activate scenario form
steps:
- intent: play_scenario
- action: scenario_form
- active_loop: scenario_form
- rule: submit scenario form
condition:
# Condition that form is active.
- active_loop: scenario_form
steps:
# Form is deactivated
- action: scenario_form
- active_loop: null
- slot_was_set:
- requested_slot: null
# The actions we want to run when the form is submitted.
- action: action_start_scenario
Here’s a log of the issue (with only difference that it also added an entity to the button payloads):
