[Authoring] Adaptive Card Expression is not being evaluated with .NET SDK using AdaptiveCards.Templating 2.0.4 nuget

Target Application

BotFramework WebChat

Application Operating System

Linux

Schema Version

1.5

Problem Description

We are using pre-built functions to round of time to next 15 mins Pre-built

The expression in JSON schema is

{
"type": "Input.Time",
"id": "fromDateTimeId",
"value": "${{if(empty(fromDateTime), convertFromUTC(formatTicks(mul(ceiling(div(int(ticks(addMinutes(utcNow(),15))),9000000000)),9000000000)), timeZone, 'HH:mm'), formatDateTime(fromDateTime, 'HH:mm'))}}"
}

Same JSON schema is working in Adaptive Card designer

Expected Outcome

Expecting the expression is evaluated and time is set in the field as in the designer

Actual Outcome

However the JSON schema is interpreted and parse as follows

{"type":"Input.Time","id":"fromDateTime","value":${${if(fromDateTime == null || fromDateTime == '', convertFromUTC(formatTicks(mul(ceiling(div(int(ticks(addMinutes(utcNow(),15))),9000000000)),9000000000)), timeZone, 'HH:mm'), formatDateTime(fromDateTime, 'HH:mm'))}}},{"type":"TextBlock","text":"End Time","wrap":true}

Card JSON

{"type":"AdaptiveCard","$schema":"http://adaptivecards.io/schemas/adaptive-card.json","version":"1.5","body":[{"type":"Container","id":"plaintextbox","items":[{"type":"TextBlock","text":"Sure, Please select the title, date \u0026 time for the meeting.","color":"Dark","wrap":true}]},{"type":"Container","id":"formfield","items":[{"type":"TextBlock","text":"Add Title"},{"type":"Input.Text","id":"meetingTitle","maxLength":50,"value":"Team Meeting Created By Bot"},{"type":"TextBlock","text":"Date"},{"type":"Input.Date","id":"date","value":"2025-01-10","placeholder":"Enter a date"},{"type":"TextBlock","text":"Start Time","wrap":true},{"type":"Input.Time","id":"fromDateTime","value":${${if(fromDateTime == null || fromDateTime == '', convertFromUTC(formatTicks(mul(ceiling(div(int(ticks(addMinutes(utcNow(),15))),9000000000)),9000000000)), timeZone, 'HH:mm'), formatDateTime(fromDateTime, 'HH:mm'))}}},{"type":"TextBlock","text":"End Time","wrap":true},{"type":"Input.Time","id":"toDateTime","value":${${if($root.toDateTime != null && $root.toDateTime != '', formatDateTime($root.toDateTime, 'HH:mm'), if($root.fromDateTime != null && $root.fromDateTime != '', formatDateTime(addMinutes($root.fromDateTime, defaultDurationMinute), 'HH:mm'), convertFromUTC(formatTicks(mul(ceiling(div(int(ticks(addMinutes(addMinutes(utcNow(),15),defaultDurationMinute))),9000000000)),9000000000)),$root.timeZone, 'HH:mm')))}}}]},{"type":"Container","id":"SpaceFeedbackContainer","items":[{"type":"ColumnSet","columns":[{"type":"Column","width":"auto","items":[{"type":"ActionSet","actions":[{"type":"Action.Submit","title":"Confirm","associatedInputs":"auto"}]}]},{"type":"Column","width":"auto","items":[{"type":"ActionSet","id":"whiteBtn","actions":[{"type":"Action.Submit","title":"Cancel","associatedInputs":"none"}]}]}]}]}]}

using following method in .NET solution

private AdaptiveCard GenerateAdaptiveCard(string contentPath, string cardData) { if (string.IsNullOrWhiteSpace(contentPath)) throw new ArgumentNullException(nameof(contentPath)); /*if (!string.IsNullOrWhiteSpace(cardData)) throw new ArgumentNullException(nameof(cardData));*/ var cardTemplate = File.ReadAllText(contentPath); var template = new AdaptiveCardTemplate(cardTemplate); var cardJson = template.Expand(cardData); //return cardJson; //// Parse the JSON AdaptiveCardParseResult result = AdaptiveCard.FromJson(cardJson); //// Get card from result AdaptiveCard card = result.Card; //card.Version = new AdaptiveSchemaVersion("1.3"); return card; ////var cardJson = new AdaptiveTransformer().Transform(cardTemplate, cardData); ////return AdaptiveCard.FromJson(cardJson).Card; }

public Activity GetActivityMessageForAdaptiveCard(string contentPath, string cardData) { if (string.IsNullOrWhiteSpace(contentPath)) throw new ArgumentNullException(nameof(contentPath)); /*if (!string.IsNullOrWhiteSpace(cardData)) throw new ArgumentNullException(nameof(cardData));*/ var adaptiveCard = this.GenerateAdaptiveCard(contentPath, cardData); var attachment = new Microsoft.Bot.Schema.Attachment { ContentType = AdaptiveCard.ContentType, Content = JsonConvert.DeserializeObject(JsonConvert.SerializeObject(adaptiveCard)) //JsonConvert.DeserializeObject(adaptiveCard) }; var message = MessageFactory.Text(string.Empty); message.Attachments = new List<Attachment> { attachment }; message.InputHint = InputHints.IgnoringInput; ////message.Text = AdaptiveCardSpeakMessage.DefaultMessage; ////message.Speak = AdaptiveCardSpeakMessage.AdaptiveCardUserNotification; return message; }

var cardDataPath = "./Resources/MeetingDateTimeSelectionData.json"; var cardData = File.ReadAllText(cardDataPath);//JsonConvert.DeserializeObject(File.ReadAllText(cardDataPath)); //var cardTemplateData = JsonConvert.SerializeObject(cardData); var cardTemplatePath = "./Resources/MeetingDateTimeSelectionTemplate.json"; //await stepContext.Context.SendActivityAsync(GetActivityMessageForAdaptiveCard(cardTemplatePath, cardData), cancellationToken); await stepContext.Context.SendActivityAsync(GetActivityMessageForAdaptiveCard(cardTemplatePath, cardData), cancellationToken);
