BotFramework 网络聊天频道无法渲染卡片

Question

I'm having difficulties creating a card which uses AdaptiveShowCardAction . When I try to create a simple card, it manages to show.

Code:

public override AdaptiveCard CherwellCard(UserProfile userProfile)
{
    try
    {
        foreach (var service in CherwellCategories)
        {
            var serviceCard = new AdaptiveShowCardAction()
            {
                Title = service.Name,
                Card = new AdaptiveCard()
                {
                    Body = new List<AdaptiveElement>()
                {
                    new AdaptiveTextBlock()
                    {
                        Text = TranslateHelper.GetText(userProfile.Locale, "ticket_category"),
                        Weight = AdaptiveTextWeight.Bolder,
                        Size =  AdaptiveTextSize.Medium
                    }
                },
                    Actions = new List<AdaptiveAction>()
                    {

                    }
                }
            };
            foreach (var category in service.Categories)
            {
                var categoryCard = new AdaptiveShowCardAction()
                {
                    Title = category.Name,
                    Card = new AdaptiveCard()
                    {
                        Body = new List<AdaptiveElement>()
                    {
                        new AdaptiveTextBlock()
                        {
                            Text = TranslateHelper.GetText(userProfile.Locale, "ticket_sub_category"),
                            Weight = AdaptiveTextWeight.Bolder,
                            Size =  AdaptiveTextSize.Medium
                        }
                    },
                        Actions = new List<AdaptiveAction>()
                        {
                        }
                    }
                };
                foreach (var subCategory in category.Categories)
                {
                    var subCategoryCard = new AdaptiveShowCardAction()
                    {
                        Title = subCategory.Name,
                        Card = new AdaptiveCard()
                        {
                            Body = new List<AdaptiveElement>()
                        {
                            new AdaptiveTextBlock()
                            {
                                Text = TranslateHelper.GetText(userProfile.Locale, "ticket_selection"),
                                Weight = AdaptiveTextWeight.Bolder,

                            }
                        },
                            Actions = new List<AdaptiveAction>()
                            {
                            }
                        }
                    };
                    var ContinueDataJson = "{ \"Service\" : \"{0}\", \"Category\" : \"{1}\", \"SubCategory\" : \"{2}\"}";
                    ContinueDataJson = ContinueDataJson.Replace("{0}", service.Name).Replace("{1}", category.Name).Replace("{2}", subCategory.Name);

                    var finalCard = new AdaptiveShowCardAction()
                    {
                        Title = TranslateHelper.GetText(userProfile.Locale, "ticket_details"),
                        Card = new AdaptiveCard()

                        {
                            new AdaptiveTextBlock()
                            {
                                Text = TranslateHelper.GetText(userProfile.Locale, "ticket_services"),
                                Weight = AdaptiveTextWeight.Bolder,

                                Text = category.Name,
                                Weight = AdaptiveTextWeight.Lighter,
                                Size =  AdaptiveTextSize.Medium

                            new AdaptiveTextBlock()
                            {
                                Text = subCategory.Name,
                                Weight = AdaptiveTextWeight.Lighter,
                                Size =  AdaptiveTextSize.Medium
                            }
                        },
                            Actions = new List<AdaptiveAction>()
                        {
                            new AdaptiveSubmitAction()
                            {
                                Title =  TranslateHelper.GetText(userProfile.Locale, "ticket_submit"),
                                DataJson = ContinueDataJson
                            }
                        }
                        }
                    };

                    subCategoryCard.Card.Actions.Add(finalCard);

                    categoryCard.Card.Actions.Add(subCategoryCard);
                }
                serviceCard.Card.Actions.Add(categoryCard);
            }
            serviceAction.Add(serviceCard);
        }

        AdaptiveCard card = new AdaptiveCard()
        {
            Body = new List<AdaptiveElement>()
        {
            new AdaptiveTextBlock()
            {
                Text = TranslateHelper.GetText(userProfile.Locale, "ticket_services"),
                Weight = AdaptiveTextWeight.Bolder,
                Size =  AdaptiveTextSize.Medium
            }
        },
            Actions = new List<AdaptiveAction>()
            {
            }
        };
        card.Actions.AddRange(serviceAction);

        return card;
    }
    catch (Exception ex)
    {

        throw;
    }

}

For the CherwellCategories list - it contains 3 levels, Service (8 data) - Category (20+) and SubCategory (118 data). I'm suspecting it's because the card is way too big for it to process.

The card is not shown when I click on the button. It doesn't give any response. Is there any limit or something? As I'm able to create a simple card and show it, continue with the flow of the dialog.

Answer 1

I remove 3 out of the 7 service (along with the subsequent category and subcategory belonging to the 3 service removed), and it works also. If i remove only 2, then it cannot render anymore.

I do a test using the same data as the json value that you provided, I can reproduce same issue in web chat. And I checked the size of the activity that contains the generated adaptive card as attachment, it is about 430kb .

As you mentioned, if I remove some items (services) from service list, the card can be rendered and work as expected. It seems that some limitations of activity or adaptive card cause this issue, currently we can not find any documentation explains about similar issue, if possible, you can create an issue to report it.

Besides, your show many of services, categories and sub_categories for user selecting in one adaptive card, as a workaround, you can try to separate them in many adaptive cards, and then you can dynamically display child adaptive card(s) based on user's selections and post back value that you collect in previous adaptive card.
