Hello, I'm experiencing some problem with your library. I'm using your code to recognize the action after a request:

My intent action return "tell.popular" (this is the request that Dialogflow sends):

{
  "responseId": "589e1fb4-56b6-4377-8944-16b442090958",
  "queryResult": {
    "queryText": "popolare",
    **"action": "tell.popular",**
    "parameters": {
      "Filtro": "Popolarità"
    },
    "allRequiredParamsPresent": true,
    "fulfillmentMessages": [
      {
        "text": {
          "text": [
            ""
          ]
        }
      }
    ],
    "intent": {
      "name": "projects/nespressoadvisor/agent/intents/bb7a2662-2851-4d68-bb86-92d368b6d195",
      "displayName": "choose_popular"
    },
    "intentDetectionConfidence": 1,
    "diagnosticInfo": {},
    "languageCode": "it"
  },
  "webhookStatus": {
    "message": "Webhook execution successful"
  }
}

and here is the code. Unfortunately it doesn't work and I can't find a way to check the whole flow from handleRequest(actionMap) and check how is managed the request.

Furthermore, if I try to evaluate the DialogflowAction(req, res).handleRequest(actionMap) line during debug, it returns me "undefined". (???)

Could you help me?

const val POPULAR = "tell.popular"

@WebServlet(name = "Hello", value = "/")
class HomeController : HttpServlet() {

    val actionMap = mapOf(POPULAR to ::popular)


    fun popular(app: DialogflowApp) =
            app.ask(app.buildRichResponse()
                    .addSimpleResponse(speech = "Hi there!", displayText = "Hello there!")
                    .addSimpleResponse(
                            speech = """I can show you basic cards, lists and carousels as well as suggestions on your phone""",
                            displayText = """I can show you basic cards, lists and carousels as well as suggestions""")
                    .addSuggestions("Basic Card", "List", "Carousel", "Suggestions"))



    override fun doPost(req: HttpServletRequest, res: HttpServletResponse) {


        DialogflowAction(req, res).handleRequest(actionMap)

    }

Using the following code:

@PostMapping("/")
fun intentMapper(req: HttpServletRequest, res: HttpServletResponse) {
    DialogflowAction(req, res).handleRequest(mapOf("testAction" to ::test))
}

fun test(action: DialogflowApp) {
    action.tell(speech="Text to speech", displayText="Text to display")
}

the response body fullfilment looks like this:

"fulfillment": {
      "speech": "Text to speech",
      "source": "",
      "displayText": "",   <-------------------------------- SHOULD NOT BE EMPTY
      "messages": [
        {
          "type": 0,
          "speech": "Text to speech"
        }
      ],
      "data": {
        "google": {
          "isSsml": false,
          "noInputPrompts": [],
          "expectUserResponse": false,
          "richResponse": {
            "items": [
              {
                "simpleResponse": {
                  "textToSpeech": "Text to speech",
                  "displayText": "Text to display"
                }
              }
            ],
            "suggestions": []
          }
        }
      }
    }

We can access to the displayText of fulfillment.data.google.richResponse.items[0].simpleResponse.displayText.

However, I was expecting the same text in displayText at fulfillment.displayText like fulfillment.speech, but it is empty.

Just getting started on google actions v2. Wondering if you consider this library is stable enough to use?

The problem

Hi Patrick, I know you will hate me for all these issues 😛 but I'm experiencing other problems with your sample.

In fact, if I say "list" or "basic card" it doesn't catch the appropriate intent. Furthermore, ANY response tested on Google Assistant simulator gives me error and tells me 'final_response' must be set.

The problems is obviously extended also on my projects: in fact none of the samples copied and paste on my code don't work on Google Assistant simulator.

Some debugging

I've tried to write down manually the same structure of JSON for the response and here is what i found:

Manually built response through Google Assistant tab on Dialogflow

                        }

                     {
                        "title":"hi"
                     }
                  ]

   "sessionId":"adf3ea83-cc0e-410c-b642-28300d81549a"
}

As you can see, in the fulfillment object is really different for the "messages" and "data" object: what's happening?

The presence of isEmpty() causes some kotlin JSON parsers (e.g. fasterxml as used by AWS Lambda) to generate a field labelled 'empty' because isEmpty() follows the pattern of a boolean accessor.

Hi, I've been struggling with this for a few days now.

askForUpdatePermission doesn't find my intent even though it is clearly there. Can someone please help point in the right direction?

1. askForUpdatePermission not finding intent

I followed the Update Sample at https://github.com/actions-on-google/dialogflow-updates-nodejs and got the update permission to work.

But when I added app.askForUpdatePermission("get.next.reminder") into my own code, the simulator says that my agent is not responding. I did not get the question to give update permission.

In the simulator error tab, I see an error:

MalformedResponse expected_inputs[0].possible_intents[0].input_value_data: The intent the app is asking for permission to send updates for is not found.. So I checked the intent name (get.next.reminder) again in my agent and it is clearly there and mapped to an action. I also tested that this intent can be triggered by user input.

The response tab shows the response like this:

{ "conversationToken": "["actions_on_google"]", "expectUserResponse": true, "expectedInputs": [ { "inputPrompt": { "richInitialPrompt": { "items": [ { "simpleResponse": { "textToSpeech": "PLACEHOLDER_FOR_PERMISSION" } } ] } }, "possibleIntents": [ { "intent": "actions.intent.PERMISSION", "inputValueData": { "@type": "type.googleapis.com/google.actions.v2.PermissionValueSpec", "permissions": [ "UPDATE" ], "updatePermissionValueSpec": { "intent": "get.next.reminder" } } } ] } ], "responseMetadata": { "status": { "message": "Success (200)" }, "queryMatchInfo": { "queryMatched": true, "intent": "d7edc1c1-1c67-49af-89bb-37e17ed35025" } } } Where I see PLACEHOLDER_FOR_PERMISSION in the response text.

Not sure why it is not finding the intent. Can anyone please please help with this?

2. How to remove permissions?

Also, a separate but related question: once you give the permission, how can you remove it? This is really important to be able to test.

Thank you.

Hi,

hope find you well with this cold call.

I am an author of mocking framework for Kotlin

I see you are using mockito-kotlin.

I just want you to be aware that there is solution that fully supports Kotlin and ask to try it in your new/current projects.

I can help you if you answer to this issue.

Thanks and please star it

I have been working on a google app engine project using the v2 branch. Looking for some guidence. I copied the DialogflowWebhook example and got a late init error that went away when I set Serializer.aogGson = Gson()

now I'm getting this exception

Uncaught exception from servlet java.lang.Error: No response has been set. Is this being used in an async call that was not returned as a promise to the intent handler? at actions.service.actionssdk.conversation.Conversation.response(Conversation.kt:391) at actions.service.dialogflow.DialogflowConversation.commonPayload(Conv.kt:321) at actions.service.dialogflow.DialogflowConversation.serialize(Conv.kt:366) at actions.service.dialogflow.DialogflowSdk$handler$1.handle(Dialogflow.kt:450) at actions.framework.StandardHandler$DefaultImpls.handle$default(Framework.kt:51) at actions.expected.ServletHandler.handle(BuiltinFrameworks.kt:36) at actions.service.dialogflow.DialogflowSdk$1.handle(Dialogflow.kt:463) at actions.ServiceBaseApp.invoke(Assistant.kt:21) at scott.servlets.FitnessAssistantServlet.simpleDialogFlowExample(FitnessAssistantServlet.kt:30) at scott.servlets.FitnessAssistantServlet.doPost(FitnessAssistantServlet.kt:21)

My code

data class MyConversation(val temp: String? = null)
data class MyArgument(val temp: String? = null, var resultType: String? = null, var userDescision: String? = null)

class FitnessAssistantServlet: HttpServlet() {
    val logger = Logger.getLogger("TestServlet")

    @Throws(ServletException::class, IOException::class)
    override fun doPost(req: HttpServletRequest, resp: HttpServletResponse) {
        val dfApp = dialogflow<UserStorage<Any>, MyConversation, MyArgument>()
        dfApp.frameworks.add(ServletFramework())
        dfApp.intent("test") { conv -> conv.ask("Can you hear me?") }
        dfApp(req, res
    }
}

It feels like I'm missing some initialization logic somewhere, not sure where though. Thoughts?

I use a BasicCard in my Java code but the Json serialisation is not correct.
I have "formattedText$sdk" = "" instead of "formattedText" = "".

May be "internal var" the cause ?

data class BasicCard(internal var title: String = "", internal var formattedText: String = "", internal var subtitle: String? = null, internal var image: Image? = null, internal var imageDisplayOptions: ImageDisplays? = null, internal var buttons: MutableList = mutableListOf()) {

Hello, how can I trigger an event from my webhook server to Dialogflow? I need that to perform slot fulfillment via webhook.

This is the reference in Dialogflow docs: https://dialogflow.com/docs/events#invoking_event_from_webhook

Here is a temporal solution using official Node.js library: https://github.com/actions-on-google/actions-on-google-nodejs/issues/64 But I don't know how to apply that using this library.

Here is a recent pull request to the official Node.js library adding this feature: https://github.com/actions-on-google/actions-on-google-nodejs/pull/105
