Hi,

I developed a web based chatbot and iam running the rasa core http server and calling the rest API called “prase” to get the next action.

Iam getting the following response : (request / response Screen Shots)

in my domain.yml i have defined template for

utter_greet: -text ": ‘Hey, how can i hekp you’

How to get the above mentioned text to display to the user ?

After calling parse api do i need call any other API ?

I went through the Rasa_core doc and found i need to call respond API but when iam calling iam getting an Empty response.

Please help…

To get the response text directly, you can call /respond end point but you said you are getting empty response Verify the below two things

1.Have you defined story for the flow ? * greet - utter_greet

2.When you call /respond endpoint , are you passing the query parameter

Yes … the following pasted text are stories

greet

  • greet
    • utter_greet

query

    • utter_query

bye

In your log, it says remote actions can not be run locally.I think you have action_factory:remote in domain.If you have it, remove that and then train and access

Thank you… Sayam kumar… yesterday it self I removed and tried its working fine as expected… sorry forgot to update the same… but trying to understand why action_factory: remote is stopping the respond api… what it exact use of this action_factory: remote

Thank you once again

When action_factory is remote , core will only return the action names and does not run them. If you want to know more about this, you can check out the concert bot example
