[Question] prompts.choice is not working correctly with API.ai

Issue Description

I recently added NLU to my messenger bot using API.ai. I have a choice prompt in my bot (prompts.choice()), with buttons builder.ListStyle['button'].

I noticed that few of the choices are not working - and retryPrompt is invoked, and it happens because they are being matched to an intent from API.ai.

I'm looking for a solution that will isolate prompts from the NLU model or a different workaround.

P.S. I'm using IntentRecognizerSet with 2 API.ai recognizers, maybe I can add the default recognizer as the first item in the set? (not sure how)

I tried to debug the library code and it seems like onRecognize function on PromptChoice detecting the right choice, and the issue comes somewhere later.

Can you provide your code so we can see it?

[amitbend]

Sure,
the prompt looks like this:
(session, results, next) => { builder.Prompts.choice( session, 'Choose one:', Object.keys(choicesObj), { maxRetries: 1, retryPrompt: 'We do not have info regarding that subject', listStyle: builder.ListStyle['button'] }); },
It is a part of a library.

the recognizer looks like:
var r1 = new apiairecognizer('key1'); var r2 = new apiairecognizer('key2');
let set = new builder.IntentRecognizerSet({ recognizeOrder: builder.RecognizeOrder.series,stopIfExactMatch: true }) .recognizer(r1).recognizer(r2)

[stevengum]

Just to clarify, the user's response to the prompt is unrecognized because of the API.AI recognizers activating and returning matched intents?

How are you plugging set into your bot? Are you using bot.recognizers = set; ?

[amitbend]

@stevengum97 yes, I can see there is a matched intent (without any action attached)
I'm plugging it to the bot this way: bot.recognizer(set)
where bot is my universalBot

@amitbend it looks like it's similar to #2839 except you're wanting the recognizers to not fire/return an intent? You're aiming to stay inside of your current prompt and move through it without any interruptions, if I understand correctly.

To handle this using the regular LuisRecognizer, I would use .onEnabled() (sample here), but this method doesn't exist in api-ai-recognizer.

I recommend taking the source code from there and creating a custom recognizer/adding to the instantiated api-ai-recognizers a similar method. For the case that enables/disables the recognizer, a check on the dialogStack would work well. Check if its length >= 1, if so disable the recognizers, as you're in a dialog and don't want to be interrupted.

You could also create a custom prompt; this way you should be able to also ignore results from API.ai.

Since the issue is regarding api-ai-recognizer (third-party) and a solution exists for this case (LuisRecognizer.onEnabled() or creating a custom prompt) in BotBuilder SDK, I'm closing this issue for now. An alternative you could work with is placing the recognizers into an IntentDialog instead of having them at bot level, but this would change other aspects of how the bot works.

@stevengum97 thanks for the informative answer.
It seems to be a variation of #2839, in my case, it does not either switch to the other dialog that capture the intent or matching it to one of the choices.
I will check out the solutions that you've mentioned and provide an update later.

hi @stevengum can u help me in how to disable the luisRecognizer using .onEnabled() . i am not finding the solution code anywhere. Would be really helpful

Hi @vishmonne

The example @stevengum shared can be found here: https://github.com/Microsoft/BotBuilder-v3/blob/master/Node/examples/feature-onEnabled/app.js

Another example can be found here: #2670 (comment)

You can also use .onFilter, as explained here: #3530 (comment)
