FormAction on Server with Rasa X does not work

Tobias · September 29, 2020, 9:26am

Hi everyone,

could you please help me. I have just uploaded my chatbot to an server. It is currently running with docker and I have the following software packages installed:

Everything works right except for one thing. If I want to run the FormAction the chatbot does not run it correctly:

Here is my actions.py:

from typing import Dict, Text, Any, List, Union
from rasa_sdk import Tracker, Action 
from rasa_sdk.executor import CollectingDispatcher
from rasa_sdk.forms import FormAction

class SubscribeNewsletterForm(FormAction):
   
    def name(self) -> Text:
        return "abonnieren_newsletter_form"

    @staticmethod
    def required_slots(tracker: Tracker) -> List[Text]:
        return ["email"] 
    
    def submit(
        self,
        dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any],
    ) -> List[Dict]:
                       
        
        dispatcher.utter_message("Vielen Dank. Wir senden absofort hilfreiche Informationen an Ihre E-mail Adresse.")
            
        return []

how do you run your bot??? I never had don’t that but it seems that the command rasa run actions is never execute. maybe you need to put that line in you docker file?

Tobias · September 30, 2020, 8:03am

Thank you for your reply. In my actions.py I have already tested an Action. This one runs well without any problems. I don´t think that I have to run this command in docker separately?

Does anyone have a solution for my problem?

Thanks!

Would you mind sharing the output logs of rasa-sdk and rasa-production? Also, is the message you sent (“Newsletter abonnieren”) the first one in the conversation?

Tobias · October 2, 2020, 10:29am

How can I share the output logs of rasa-sdk and rasa-production? What is the command for that?`

No, I started the conversation with “Hi” as user.

@ricwo @akelad @stephens @mloubser @erohmensing
There seems to be an issue with a new event (active_loop) that rasa forms don’t recognize. I am having the same issue, it used to work but it doesn’t now. I am using rasa version 1.10.10 and rasa x version 0.32.2:

Hi @ricwo,

do you have any recommandations so far?

ricwo · October 14, 2020, 2:43pm

@Tobias it would still be great to see your logs for rasa-production and rasa-sdk. To get those, please run sudo docker ps -a and then run sudo docker logs <X>, substituting the names of the two containers for <X>

ricwo · October 14, 2020, 2:48pm

@basil-chatha The active_loop event was introduced in Rasa 2.0. Please check out the docs on Forms

Tobias · October 19, 2020, 12:13pm

Here are the logs for production:

Here for rasa-sdk:

geniuslead · December 19, 2020, 3:53pm

I had the same issue where form action wasn’t found I followed (Ep #9 - Rasa Masterclass) Improving the assistant: Setting up the Rasa X | Rasa 1.8.0 - YouTube.

Didn’t follow any other steps of creating action server separately

Finally - all started working

Get Action server Image container Id by running

Run : sudo docker ps

The container Id 603339fd04e0 is mapped to Image: rasa/rasa-sdk:latest
COMMAND : "./entrypoint.sh Ports : 5055/tcp

Run: docker container restart 603339fd04e0

This is the action server, I restarted then Rasa X was able to find the actions registered, and is responding.
