Error creating Azure BOT: Failed to store new BOT

SCENARIO

You are trying to create Azure BOT where you are already provided with an existing App registration. After adding relevant details, validation is passed however, the BOT fails to create with Internal Server error. 

CAUSE

This error usually comes up if we are using the same APP ID which is already registered with another Azure BOT resource. 

{

    "status": "Failed",

    "error": {

        "code": "UnknownError",

        "message": "Failed to store new bot."

    }

}

RESOLUTION

Azure BOT requires one to one mapping with the app registration. You can only have one BOT mapped to one App ID.

Hence recommendation is to use single app registration for every BOT resource we create.
