Issue with Rasa Pro 3.8.10: "IndexError: list index out of range" During Training for Chat With Your Text Documents

Hi everyone,

I’ve been working with the Rasa sample project “Chat With Your Text Documents” and it was running fine with Rasa Pro 3.7.10. However, after upgrading to version 3.8.10, I encountered an error during training with the following message:

I’ve tried several solutions but haven’t been able to resolve this issue. Has anyone encountered a similar problem or have any suggestions on how to fix this?

Thank you very much!

This can happen when no flows are defined. Can you define two simple flows and try again?

I have already defined a flow in the flows.yml file. image

In Rasa Pro version 3.7.10, I observed that the FAISS class from site-packages/langchain/vectorstores/faiss.py is used in the site-packages/rasa_plus/information/retrieval/faiss.py file.

In Rasa Pro version 3.8.10, however, I don’t see that class being called anywhere. When I tried logging it, the embedding list was empty. Could this be an issue?

I also checked the package and found that rasa_pro does not contain the necessary files to run the program
