We are getting forbidden message exception while sending message from Teams groups to webchat.
Seeing the below error log in Azure bot channel,
Webchat: There was an error sending this message to your bot: HTTP status code InternalServerError
Directline : There was an error sending this message to your bot: HTTP status code GatewayTimeout
Teams : Error occurred while communicating with bot
But we are able to send messages from Webchat to Teams, Teams to Teams , Teams to Emulator.
Issue only when sending message from Teams to Directline/Webchat
