Microsoft Teams Bot Adaptive card not rendering in mobile app (android)

Question

Microsoft Teams Bot - Adaptive card not displaying in android mobile app, it works fine in desktop app, json as below, also other card for list of records works, is that something to with empty text columns? Checked with 'adaptivecards.io' not issues reported.

JSON added here https://jsfiddle.net/yaorm2en/

Answer 1

I found the answer. If the Action.OpenURL does not contain a valid link, the Teams mobile app will not show the whole adaptive card, but the desktop app will.

Answer 2

I am able to solve it, problem is null values in data, it does not produce json "text" property, replacing null values with empty string works
