Hi, Can some one help me how to handle this.

i.e., when I send an image to messenger, how can I load that image and use that in a custom action?

As of right now, we don’t support parsing images, since the bot wouldn’t know what to do with that information coming in, as all incoming information is parsed as a UserMessage and expects test for parsing, not a url or bytes.

Is there a way an error message be popped up by the bot saying “Sorry I can’t handle this”

You could extend the facebook channel, so that here:

github.com

RasaHQ/rasa/blob/master/rasa/core/channels/facebook.py#L89


    # quick reply and user message both share 'text' attribute
    # so quick reply should be checked first
    if self._is_quick_reply_message(message):
        text = message["message"]["quick_reply"]["payload"]
    elif self._is_user_message(message):
        text = message["message"]["text"]
    elif self._is_audio_message(message):
        attachment = message["message"]["attachments"][0]
        text = attachment["payload"]["url"]
    else:
        logger.warning(
            "Received a message from facebook that we can not "
            "handle. Message: {}".format(message)
        )
        return


    await self._handle_user_message(text, self.get_user_id(), metadata)


async def postback(
    self, message: Dict[Text, Any], metadata: Optional[Dict[Text, Any]]
) -> None:

if there is an image, you can do something else, e.g. send an /out_of_scope message to the bot so that it can respond that the user’s request is out of scope
