Is there any way to set Slot by API not by action

Hi Folks,

I have a different requirement here. I want to set slots not by Action/Custom Action but want to set it by API.

I am using

rasa-core==0.13.8 rasa-core-sdk==0.12.2 rasa-nlu==0.14.4

Can anybody help me out?

Thanks

You can use the endpoint /conversations/<sender_id>/tracker/events. Here the link to the documentation: HTTP API

And here is an example request:

curl -X POST \
  'http://localhost:5005/conversations/default/tracker/events?include_events=NONE' \
  -H 'Content-Type: application/json' \
  -d '{"event":"slot","name":"<name-of-slot>","value":"<value-of-slot>","timestamp":0}'

Make sure to fill out <name-of-slot> and <value-of-slot> with proper values. The name of the slot should also be present in your domain file.

Thanks, @Tanja for your input. But I am still facing the same issue. It shows me that slot is set but when I called it in custom action it gives me None.

Can you please explain in more detail what exactly you are doing:

  • What commands do you execute?
  • What is the request?
  • In which order are you executing the steps?

Thanks.

Hi @Tanja

What i exactly doing is, I hit the request given by you via postman and then i tried to access it on my custom action it gives me the None.

Thanks

I have some trouble reproducing the error. I have a simple bot, that has a slot called name and an action called action_greet. I get the value of slot name and utter Hello {name}! or just Hello! depending on whether the slot is set or not in that action.

I’m executing the following steps:

  1. Start the action server
python -m rasa_core_sdk.endpoint --actions actions
  1. Start the rasa server
python -m rasa_core.run --endpoint endpoints.yml --enable_api -d models/current/dialogue -u models/current/nlu -o out.log
  1. Set the slot via the API
curl -X POST \
  'http://localhost:5005/conversations/default/tracker/events?include_events=NONE' \
  -H 'Content-Type: application/json' \
  -d '{"event":"slot","name":"name","value":"Tanja","timestamp":0}'
  1. Trigger the action
curl -X POST \
  'http://localhost:5005/conversations/default/execute?include_events=AFTER_RESTART' \
  -H 'Content-Type: application/json' \
  -d '{"name":"action_greet"}'

The last request successfully returns the message Hello Tanja!. So the slot I set before, was used in the action action_greet.

What steps are you executing?

Hello @Tanja, I’m working with RASA HTTP API, when I set slot by API the next action predicted was wrong, but in my local the next action predicted was correct. How can I fixe the order of my conversation (input user --> predict action --> execute action --> …) ?

@illi88 Can you please open a new thread for your question as your question is not related to the previous conversation but rather a complete new question. Thanks. Also please add some more information to your question, such as, what requests are you doing, what Rasa version are you using, otherwise it is hard to reproduce the problem you have.

@Tanja I had already posted the question with the title : " Wrong action predicted with RASA HTTP API ". I’ll add some updates about requests that i’m doing. The version of RASA i’m using is RASA 1.1.4

@Tanja I’m having the same problem with rasa 1.4.6 (I’m unable to upgrade to > 1.5.0 because of this bug: Loss of confidence in Rasa > 1.6.0 nlu (compared to 1.4.6) · Issue #5004 · RasaHQ/rasa · GitHub). Did you find out what was happening?

I have an action called show_profile that just utters the profile slot.

(from domain.yml)
  utter_profile:
  - text: "I am {profile}"

(from data/stories.md)
## show_profile
* show_profile
  - utter_profile

If I set the slot with /show_profile{"profile":"broker"}, Rasa starts responding correctly. If I set the slot with a call to the tracker, I keep getting fallback actions instead of conversation.

I have a slot called “Profile” (categorical), that can be “broker”, “standard” or “anon”.

Before sending any message to rest/webhook, I set the slot with this snippet:

#profile contains the string "broker"

headers = { 'Content-type':'application/json' }
payload = '{ "event": "slot", "name": "profile", "value": "' + profile + '", "timestamp":0 }'
r = requests.post(event_uri, data=payload.encode('utf-8'), headers=headers)

The problem is that the tracker gets completely lost and nearly everything calls the fallback action.

Here’s a log extract (I’m translating the intent names and text from portuguese):
