How to make a carousel using Google.Cloud.Dialogflow.V2 Carousel for dialogflow? - dialogflow-es

Question

Im trying to build a webhook for dialogflow with help from nuget package Google.Cloud.Dialogflow.V2.
Im running the code with .Net Core 2.1.
I get the fullfilmentText to show in dialogflow, but cant make the carousel to show up.
What am I doing wrong?
Here is my method:
[HttpPost]
public ContentResult Post([FromBody] WebhookRequest webhookRequest)
{
var dialogflowResponse = new WebhookResponse { FulfillmentText = "FulfillmentText" };
var carousel = new Intent.Types.Message.Types.CarouselSelect.Types.Item
{
Title = "My title",
Description = "This is a description",
Image = new Intent.Types.Message.Types.Image
{
ImageUri = "https://placekitten.com/200/300",
AccessibilityText = "cat"
},
Info = new Intent.Types.Message.Types.SelectItemInfo
{
Key = "Cats"
}
};
carousel.Info.Synonyms.Add("Synonym 1");
carousel.Info.Synonyms.Add("Synonym 1");
dialogflowResponse.FulfillmentMessages.Add(new Intent.Types.Message {
CarouselSelect = new Intent.Types.Message.Types.CarouselSelect()
});
dialogflowResponse.FulfillmentMessages.First().CarouselSelect.Items.Add(carousel);
return dialogflowResponse;
}
Generates followiing Json:
{
"fulfillmentText": "FulfillmentText",
"fulfillmentMessages": [
{
"carouselSelect": {
"items": [
{
"info": {
"key": "Cats",
"synonyms": [
"Synonym 1",
"Synonym 1"
]
},
"title": "My title",
"description": "This is a description",
"image": {
"imageUri": "https://placekitten.com/200/300",
"accessibilityText": "cat"
}
}
]
}
}
]
}

Answer 1

i ran into the same problem with the java api. Only the basic rich messages (card, quick replies, ...) are working. BasicCard, Suggestions, Carousel, ... doesn't show up in any channel.
I got it to work if i added some of the following custom payload to skype channel:
{
"skype": {
"type": "message",
"attachmentLayout": "carousel",
"text": "Please select your food.",
"attachments": [{
"contentType": "application/vnd.microsoft.card.hero",
"content": {
"title": "Sushi",
"subtitle": "Very fresh shrimp or tuna.",
"images": [{
"url": "https://i.ibb.co/87LmvT3/mdi.png"
}
],
"buttons": [{
"type": "imBack",
"title": "1 piece",
"value": "sushi,1"
}, {
"type": "imBack",
"title": "2 piece",
"value": "sushi,2"
}, {
"type": "imBack",
"title": "more",
"value": "sushi,3+"
}
]
}
}, {
"contentType": "application/vnd.microsoft.card.hero",
"content": {
"title": "Tenpura",
"subtitle": "Japanese first-class vegitables.",
"images": [{
"url": "https://i.ibb.co/87LmvT3/mdi.png"
}
],
"buttons": [{
"type": "imBack",
"title": "1 piece",
"value": "tenpura,1"
}, {
"type": "imBack",
"title": "2 piece",
"value": "tenpura,2"
}, {
"type": "imBack",
"title": "more",
"value": "tenpura,3+"
}
]
}
}
]
}}
I hope it helps!
