Solution for accessing the customData- metadata from rasa

Rasa Open Source
1

I am using rasa-webchat for UI

import Widget from 'rasa-webchat';
import avatarImage from './chatbot.png';
export function CustomWidget() {
  return (
    <Widget
      initPayload={"/utter_greet"}
      socketUrl={"http://localhost:5005"}
      socketPath={"/socket.io/"}
      customData={{"language": "en", "studentId": "123"}} // arbitrary custom data. Stay minimal as this will be added to the socket
      title={"Chatbot-beta"}
    //   subtitle={"powered by DigiTechnologyNepal"}
      storage={"session"}
      profileAvatar={avatarImage}
      fullScreenMode={true}
    />
  )
}

I want to access the information in customData from rasa. This is my credential.yaml file

socketio:
 user_message_evt: user_uttered
 bot_message_evt: bot_uttered
 session_persistence: true
 metadata_key: customData

I was trying to access the data of custonData in action.py


class CustomAction(Action):
    def name(self) -> Text:
        return "action_get_custom_data"

    def run(self, dispatcher: CollectingDispatcher,
            tracker: Tracker,
            domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
        metadata = tracker.latest_message.get("metadata")
        # retrieve customData from metadata
        custom_data = metadata.get("customData", {})
        # Access the customData
        print(custom_data)
        custom_data = tracker.latest_message.get("metadata", {}).get("customData")        
        print(custom_data)
        # Use the customData as needed
        if custom_data:
            # Use the customData as needed
            student_id = custom_data.get("studentId")
            language = custom_data.get("language")

            dispatcher.utter_message("Received customData: student_id={}, language={}".format(student_id, language))
        else:
            dispatcher.utter_message("No customData received")
        return []

but i am unable to access the customData

You can use session_started_metadata as part of the action_session_start call when the bot communication is started. The docs on this are here
