@mkauroaktreecapital - Could you please share a video of the error that you're getting. Could you please confirm if you are facing this issue even when the card is sent through Developer portal.
@Meghana-MSFT Does this bug fall to Teams? I am not able to repro on our visualizer; however, I'd need more information on the CalendarMeetingInfo object for a full repro.
@anna-dingler - Question author mentioned Microsoft Teams in Application name, however I tried to send the card through developer portal in Teams and it worked. @mkauroaktreecapital - Could you please share above asked details to @anna-dingler.

Yes, we are getting this issue from developer portal as well. Card is not rendering if I paste the cardJson which is created through code after template.Expand(). And we can see formatDateTime function not expanding properly due to which error occurs.

Sample CalendarMeetingInfo object json that is used to fill data in card is below: {"AttendeeList":null,"TimeSlotList":null,"CalendarDetails":null,"MinimumAttendeePercentage":0.0,"MeetingDuration":null,"SelectedDuration":null,"StartDateTime":null,"EndDateTime":null,"Subject":null,"Description":null,"Attendees":null,"Calendar":null,"Year":"","EventFrequency":null,"BusinessDay":null,"OtherDay":"","StartTime":"2025-02-25T17:35:08.2842369","EndTime":"2025-02-25T17:35:08.2842369","YearList":[{"Year":"2025"},{"Year":"2026"}],"submitCard":null,"QuarterlyFrequency":null,"QuarterlyOther":null,"MonthlyFrequency":null,"MonthlyOther":null,"ReturnDueToInvalidData":false,"usersMailIds":null,"CalendarID":null,"ScheduledID":0,"Delivered":false}
string cardJson = template.Expand(meetingInfoState);
In cardJson that we get after expanding the template we can see formatDateTime function as is, which is wrong. It should be able to read the startTime and convert it to HH:mm and then assign its value. This works fine with older nuget versions. Issue is with new version.
Works fine with adaptive cards designer.
@mkauroaktreecapital - Hi, I just came across this thread. Are you still encountering this issue?
