I am creating a bot for the hangout chat via C#, I was able to create simple messages and messages on cards, but I am not able to work with CARD_CLICKED.
It displays the message that could not connect to the bot, try later.
Retrieving the error message, I noticed this message:
Google.Apis.Requests.RequestError Unsupported path name in update message field mask.
How can I get this to work in C#?
