Error With Validation

Rasa Open Source
1

I am trying to create a simple bot which can tell me the price and offers on a car. It run’s fine while I do interactive training but fails afterwords (when model loaded in memory on a console) with the following error -

ERROR:main:Failed to validate slot car with action offer_form

I was under the assumption that in case of a form if NLU is not able to detect an entity it would repeat the question, but instead it throws an exception and takes a random path.

I am attaching the logs, the generated story’s and my action class for the same. Any help would be highly appreciated.actions.py (1.1 KB) error.log (8.9 KB) storys.md (2.3 KB)

Hey @harsh07patni. Apologies for the late response in this. Do you mind sharing the domaing file as well?

@Juste @harsh07patni was this ever resolved? I am having the exact same problem

For each of my stories, I had added “action_restart” at the end so that the conversation would reset after a happy path. However, this has caused failed validations to take random paths, including restarting the whole conversation. Please help!
