I'm testing "CodeBlock" in my adaptive card, but it is failing to render with the following exception:

Microsoft.Azure.ProcessSimple.Data.Entities.Exceptions.ProcessSimpleDataException: The specified Teams flowbot adaptive card request is missing or invalid. The tracking Id is '{0}'. ---> System.InvalidCastException: Unable to cast object of type 'AdaptiveCards.AdaptiveUnknownAction' to type 'AdaptiveCards.AdaptiveElement'.

When I try to paste the example CodeBlock from this document into MSFT Adaptive Card Designer (v1.5), I get the following error:

[Parse] Unknown element type "CodeBlock". Fallback will be used if present.
