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?

Hi @vi.kumar!

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

```auto
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:

> [@vi.kumar](#):
>
> ```auto
> 2020-07-08 00:14:43 DEBUG rasa.core.tracker_store - Tracker with sender_id ‘15941474813336344’ stored to database
> 2020-07-08 00:14:43 DEBUG rasa.core.lock_store - Deleted lock for conversation ‘15941474813336344’.
> 2020-07-08 00:15:19 DEBUG rasa.core.tracker_store - Can’t retrieve tracker matching sender id ‘15941475184502618’ from SQL storage. Returning `None` instead.
> 2020-07-08 00:15:19 DEBUG rasa.core.tracker_store - Tracker with sender_id ‘15941475184502618’ stored to database
> 
> ```

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?
