Hello - I'm trying build a flow that posts an adaptive card into a teams chat. I used https://adaptivecards.io/designer to generate the json but have been receiving the following error:

The request failed. Error code: 'InvalidJsonInBotAdaptiveCard'. Error Message: 'Microsoft.Azure.ProcessSimple.Data.Entities.Exceptions.ProcessSimpleDataException: The specified Teams flowbot adaptive card request is missing or invalid. The tracking Id is '{0}'. ---> Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: H. Path 'body[1].label', line 18, position 21.
