Getting warning in rasa_core.processor

Hey guys,

I am getting a warning in logs when different actions are executed. Can you please explain, should I ignore this or need to dealt with.

this warning means that your custom actions return SetSlot events that you didn’t specify in the training stories, if these slots are unfeaturized you’re fine, otherwise please use interactive training to see how the training story for this custom action should look like

3

Im getting the same error and I used interactive learning to create a training story for this, retrained the model, and the warning is still coming up.

4

do your action set a slot that is not present in the stories as SlotSet event after this action?

5

I am getting the same error. Please clarify. @akelad @Juste @Ghostvv

6

what slots your custom action returns? how the story for this action looks like?

Hey @rohitharitash I actually found the same problem happening in my code and resolved it by setting slot in the code.

`

  • action: restaurant_form
    • active_loop: restaurant_form
    • slot_was_set:
      • cuisines: Indian
      • times: 8:00pm`

How about when you’re using a rule and not a story?

At first I had both a rule and a story, and got the “conflicting stories” error, so I removed my story to just use the rule, and now it errors wanting the slot to be filled during training.

I see no way to do that in a rule because as a rule you probably don’t want to force a slot to set every time it is executed, right?

I have the same issue here. I use rules to handle the form and not stories. And I get the error.

So what is the proper way to handle this? Form by rules or stories?

I was getting the warning for the “city” slot in the rule below. Here is how I set these to get rid of the warning. It doesn’t default to “San Antonio”. My understanding is that “San Antonio” is just an example of what it should be looking for.

- rule: Ask for the weather
  steps:
  - intent: weather
  - action: weather_form
  - slot_was_set:
    - city: San Antonio
  - active_loop: weather_form

- rule: Submit request for weather
  condition:
    - active_loop: weather_form
  steps:
    - action: weather_form
    - active_loop: null
    - slot_was_set:
      - city: San Antonio
      - requested_slot: null
    - action: action_weather

Hi @csmyth76 I had the same problem and I experienced that your code solve the issue! I’d mark as RESOLVED if I wish (but I didn’t find the button in this thread :frowning:).

A note/praise for RASA team developers:

The reason why I need to specify the slots_was_set values in BOTH the rules is not clear to me and it seems NOT documented ted by example in the official RASA docs webpages, by example here: Forms

May you please add this insight in docs? :pray:

Thanks all!
