Rasa Slots gets None

Rasa Open Source
1

Hi! I have two slots “save_id” and “save_name” I want these two slots to retain its value throughout the conversation

In my stories i have like this -

*ask_save_details{“save_id”:“vi.kumar”, “save_name”:“Vivek Kumar”}
-action_save_details

inside action_save_details also-
return[SlotSet(“save_id” , emp_id) , SlotSet(“save_name”, name)]

Even forcing with a return statement doesnt hold the value

when action_save_details is run , it picks the value
But as soon as other query i runs these two slots are None

Kindly help me

Hi @vi.kumar!

Just to confirm, are they getting set to None before action_restart or after?

3

when i check the rasa logs which come through this command -
rasa run --enable-api -m models/dialogue -m models/nlu/current --debug --endpoints endpoints.yml --cors “*”
i dnt get any log of “action_restart”

can u plz help me how to check whether action_restart is even called or not ?

Hi @vi.kumar!

action_restart should appear in your debug logs. It should look something like this:

DEBUG    rasa.core.processor  - Predicted next action 'action_restart' with confidence

Hlo Saurabh-m523
I have given u the logs i am getting .
U can see there are three slots {id , my_id , save_id}.
initially , my_id and save_id are filled wuth value “vi.kumar”

but afterwards ther are filled to none
U told me there must be an “action_restart” action which is running i cant see any kind of log related to this

For your information , in my actions.py file and in stories i have nowhere set my_id and save-id to None but still my slots are getting none
kindly help

Hi @vi.kumar!

I’m not an expert but I have a few suggestions for debugging this:

Here, why the sender id is changing in between conversation? What channel are you using for communication? Also based on this log, I think you are using SQL tracker store. If so, then just as an experiment, could you please try disabling the tracker store and then see if you still get the same error?

Hi saurabh
It is solved
actually the sender id was changing
thank you
