FormAction on Server with Rasa X does not work

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

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"

    def required_slots(tracker: Tracker) -> List[Text]:
        return ["email"] 
    def submit(
        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?

Thank you for your reply. In my 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?


Hi @Tobias, what does your training data look like? Can you share the part of stories.yml that is relevant to this form?

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?

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.

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?

@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>

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

Here are the logs for production:

Here for rasa-sdk:

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 : "./ 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.
