Hello rasa fans! I have a customized channel that works like the callback channel. I needed to customize it so I could extract metadata from the user message. I tried to create a custom Chanel based on Callback input with the extract_metadata method. However is not working, Can you help me: This is my InputChannel: class Cisco360Input(RestInput): @classmethod def name(cls) -> Text: return "cisco360" @classmethod def from_credentials(cls, credentials: Optional[Dict[Text, Any]]) -> InputChannel: return cls(EndpointConfig.from_dict(credentials)) def __init__(self, endpoint: EndpointConfig) -> None: self.callback_endpoint = endpoint def blueprint( self, on_new_message: Callable[[UserMessage], Awaitable[Any]] ) -> Blueprint: callback_webhook = Blueprint("callback_webhook", __name__) @callback_webhook.route("/", methods=["GET"]) async def health(_: Request) -> HTTPResponse: return response.json({"status": "ok"}) @callback_webhook.route("/webhook", methods=["POST"]) async def webhook(request: Request) -> HTTPResponse: sender_id = await self._extract_sender(request) text = self._extract_message(request) metadata = self._extract_metadata(request) # method to get metadata collector = self.get_output_channel() await on_new_message( UserMessage(text, collector, sender_id, input_channel=self.name(), metadata=metadata) ) return response.text("success") return callback_webhook def get_output_channel(self) -> CollectingOutputChannel: return Cisco360Output(self.callback_endpoint) def _extract_metadata(self, req: Request) -> Optional[Text]: self.custom_metadata = req.json.get("metadata", {}) return req.json.get("metadata", None)
