[BUG] FAISS vectore store requests docstore.json

[nicolasduerr]

Describe the bug When using the FAISS node with an existing faiss.index file, I run into the issue that it requests a "docstore.json". When creating the FAISS index file with langchain, there's no docstore.json saved to disk. The documentation says that the docstore is part of the index-file itself.

The error in the chat window states:

Error: ENOENT: no such file or directory, open '/Users/.../.../faiss/docstore.json'

To Reproduce

1. Add a FAISS vector store node
2. Provide the path where the faiss.index file is stored
3. Attach e.g. Azure OpenAI Embeddings node
4. Run the chat and ask a question

Expected behavior

• I want to use the plain FAISS index file

Setup

• Installation: yarn start
• Flowise Version: 1.25
• OS: macOS
• Browser: Chrome

Additional context Please add documentation how to use this node and the specific file names and file-types that are needed.
