same error here

I am using the "Post a message as flow bot to a channel" connector, and it works well before, recently it fails with below error message. I was trying it many times, but it still not work for me. Any idea?

 

Request to the Bot framework failed with error: '{"error":{"code":"BotNotInConversationRoster","message":"The bot is not part of the conversation roster."}}'.
