Getting slot values from a conversation with sender id

Rasa Open Source
1

Hi, I have a use case where I want to extract slot values from a conversation using API. I tried with /conversations/<sender_id>/tracker but it gives all slot values as null.

When I write a custom action and pass on slot values to my server using tracker.current_slot_values(), i am able to get right slot values.

Is there a way I can accomplish this?

Hello @ankur1708, welcome to the community!!

What port, etc are you sending to? This works ok for me out of the box with a basic setup and hitting the Rasa server API endpoint:

http://localhost:5005/conversations/3b2e8ce1fea6418e889c948843ab4e37/tracker where the 3b2 value is my sender_id/convo

That gives me back the expected response data ok:

Are you using the in-memory tracker or do you have a external one setup out of curiosity?

Thanks @btotharye.

I am using rasa’s default tracker and I am able to get the information about intents etc, but not slots :frowning:

I am using a form and setting the value of slot using user input. The slot value is getting set properly (I’ve verified that by using utterance with {slot_name}), but I am not able to get that value in API.

Or, is there an API where I can get current slot values in a conversation?

ah ok let me test with my form bot and see what I get

Hi, try using Tracker.current_slot_values(). Before that add: from rasa_sdk import Tracker.

What is the exact code to send this request and receive that json response?
