Error: The following directives are not supported: DelegateDirective

Hi there,

I'm using intent chaining to switch to my dialog from the launchRequest. This works fine so far.

But sometimes there are different launchrequests, as I see in the logs. When my skill tries to delegate from these launchrequests, I get an invalid response error message from amazon, stating that "The following directives are not supported: DelegateDirective".

These different launch requests look like:

"request": {
        "type": "LaunchRequest",
        "requestId": "amzn1.echo-api.request.824a40b8-557f-49cb-b2d1-f4f1b557a77a",
        "timestamp": "2019-03-10T12:41:32Z",
        "locale": "de-DE",
        "target": {
            "path": "",
            "address": "amzn1.ask.skill.adbae884-2f1c-44c7-bcf9-289059cc7cba"
        },
        "metadata": {
            "referrer": "amzn1.alexa-speechlet-client.DOMAIN:A2S"
        },
        "body": {},
        "payload": {},
        "targetURI": "alexa://amzn1.ask.skill.adbae884-2f1c-44c7-bcf9-289059cc7cba/",
        "launchRequestType": "FOLLOW_LINK_WITHOUT_RESULT",
        "shouldLinkResultBeReturned": false
    }

What is the difference between these launch requests? And why I can't delegate this type of launch request?

greets, kobi

Hi Kobi,

thanks for posting. I would need the following information:

- Skill-ID
- Sample utterance that generated the attached JSON
- Code snippet of the LaunchRequest_Handler when you build the response

Thanks,
Gaetano

I think I've stumbled on the same problem. I can replicate it locally. It happens when I use 'activate' to start my skill, instead of the skill invocation name.

This utterance fails:

"activate (my skill name)"

Alexa response is "OK, activating (my skill name)"

The skill is invoked with LaunchRequest, and fails with the error "The following directives are not supported: DelegateDirective"

If I instead invoke my skill with 'ask (my invocation name)' then LaunchRequest is invoked and the skill works without the delegation error.

Skill ID amzn1.ask.skill.17be92cf-6a62-48db-8a69-2dde06381b60

The cope snippet is

     return handlerInput.responseBuilder
        .addDelegateDirective({
            name: 'NextTrainFromIntent',
            confirmationStatus: 'NONE',
            slots: slotWrapper.getDelegationSlotParameterFromResolvedSlotValues()
        })
        .speak(speakOutput)
        .getResponse();

The code doesn't seem to be the problem as the delegate directive works when the skill is invoked with the invocation name rather than with the 'activate' utterance.

Please check if the LaunchRequest looks like the one mentioned here when the issue happens, so I can understand the context better.

Thanks,

Gaetano

Yes, it does.

Here's the request:

"request": {
        "type": "LaunchRequest",
        "requestId": "amzn1.echo-api.request.5803c789-2aa4-4b71-a3e9-9f7b7cd4f147",
        "timestamp": "2020-08-29T15:52:19Z",
        "locale": "en-GB",
        "target": {
            "path": "",
            "address": "amzn1.ask.skill.8cc19ad3-7bf3-4497-865b-f2c5f67fbb3c"
        },
        "metadata": {
            "referrer": "amzn1.alexa-speechlet-client.DOMAIN:A2S"
        },
        "body": {},
        "payload": {},
        "targetURI": "alexa://amzn1.ask.skill.8cc19ad3-7bf3-4497-865b-f2c5f67fbb3c/",
        "launchRequestType": "FOLLOW_LINK_WITHOUT_RESULT",
        "shouldLinkResultBeReturned": false
    }

Hi Gaetano,

the skill-id is amzn1.ask.skill.adbae884-2f1c-44c7-bcf9-289059cc7cba.

I don't know the utterance of this launchrequest I posted, because it is generated by a user, not by me.

When the launch request is handled by my skill, it sends:

{
    "version": "1.0",
    "response": {
        "shouldEndSession": false,
        "directives": [
            {
                "type": "Dialog.Delegate",
                "updatedIntent": {
                    "name": "CalcTrafficLight",
                    "confirmationStatus": "NONE"
                }
            }
        ]
    }
}

As I said before, this works for a normal launchrequest. But I don't know how to handle these other launchrequests.

Thanks,

kobi

Hi,

the updatedIntent field is used to "append" the execution of another Intent after having fulfilled one.

In fact, the posted JSON doesn't look like a LaunchRequest. Are you implement Intent Chaining?

As mentioned in the previous message, sharing the LaunchRequest handler would be helpful.

Thanks,
Gaetano

Were you able to fix this problem, I'm having the same issue. Thx!

Hello,

can you share some information about your skill? Are you implementing intent chaining as well?

Thanks,
Gaetano

Yes, I'm using intent chaining, I get the error, "The following directives are not supported: DelegateDirective ".

Here is the code for the launch intent.

Note this error occurs in all three interaction models for the skill, en-US, en-CA, and fr-CA.

I'm unable to look at the "Intent history" to exactly see what the user uttered as the skill does not meet the "10 or more active users in a day" criteria.

'use strict'
const sanitizeHtml = require('sanitize-html')
const SESSION_KEYS = require('../../constants').SESSION_KEYS


const LaunchRequestHandler = {
  canHandle (handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'LaunchRequest'
  },
  handle (handlerInput) {
    const { attributesManager } = handlerInput

    const requestAttributes = attributesManager.getRequestAttributes()
    const sessionAttributes = attributesManager.getSessionAttributes()

    const speechText = requestAttributes.t('SPEECH_TXT_VEHICLE_WELCOME_MSG')
    // show welcome speech on card
    const cardText = `${sanitizeHtml(speechText, sanitizeHtml(speechText, { allowedTags: [], allowedAttributes: {} }))} ${requestAttributes.t('CARD_TXT_VEHICLE_WELCOME_FOLLOW_UP_QUESTION')}`
    const cardTitle = requestAttributes.t('CARD_TXT_VEHICLE_WELCOME_TITLE')
    sessionAttributes[SESSION_KEYS.CurrentIntentLocation] = 'LaunchRequest'
    // store welcome text so we can repeat it. welcome text is dynamic reason why we need to store it versus get straight from resource
    sessionAttributes[SESSION_KEYS.LAUNCH_INTENT_SPEECH_TXT] = speechText

    return handlerInput.responseBuilder
      .speak(speechText)
      .withSimpleCard(cardTitle, cardText)
      .addDelegateDirective({
        name: 'GetVehicleMakeAndModelIntent',
        confirmationStatus: 'NONE',
        slots: {}
      })
      .getResponse()
  }
}

module.exports = LaunchRequestHandler

I'm getting the same error. All other LaunchRequests are handled correctly by Alexa except ones received with this extra; "launchRequestType" : "FOLLOW_LINK_WITHOUT_RESULT" and "referrer" : "amzn1.alexa-speechlet-client.DOMAIN:A2S". Are these generated by Amazon directly as part of a referral from another skill?

I don't want users to think that my skill is broken.

Hi,

The addDelegateDirective() function is not supported from the LaunchRequest, to get this working, the Intent you are chaining from must have a dialog delegation strategy, which is only available for Intents that contain slots.

Hope that helps.

Thanks for the reply, however, that doesn't make sense to me. My LaunchRequestHandler implements RequestHandler and 99% of the time works when I call addDelegateDirective(intent). It only fails when the LaunchRequestHandler receives the LaunchRequestType of "FOLLOW_LINK_WITHOUT_RESULT". This LaunchRequestType isn't usually sent from devices like EchoDot, so I was wondering if this was generated from a different device that does not expect a delegation.

For example, in the documentation it says that you can return a delegate directive: https://developer.amazon.com/en-US/docs/alexa/custom-skills/request-types-reference.html#valid-response-types from the LaunchRequest.

Hi,

sorry for the miss understanding.

I can see that you have already addressed that from this post.

Thanks,
