Why does Microsof Teams webhook integration still not work after O365 connector change

[Scott Baierwalter]

The json payload (format) that is being sent from Statuspage is still not compatible with MS Teams after the O365 connector change.  I've recreated new webhooks and consistently receiving error message and Failed action inside of my workflows in MSFT.

Error messages contain:
 - Attachment is 'null'  

- Action 'Post_card_in_a_chat_or_channel_1' failed: Microsoft.Azure.ProcessSimple.Data.Entities.Exceptions.ProcessSimpleDataException: The specified Teams flowbot adaptive card request is missing or invalid. The tracking Id is '{0}'. ---> AdaptiveCards.AdaptiveSerializationException: Property 'type' must be 'AdaptiveCard'
