I have already defined a flow in the `flows.yml` file. ![image](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/3X/5/8/58b38313fe555fc26f81840abd1303d28cfdd7c9.png)

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
