I have FAISS vector database and I am using those vector databases for Query engine. However, I like to use RecursiveRetriever in 'RAGStringQueryEngine'. While I am creating RecursiveRetriever, program is asking 'node_dict' and I am not sure how I get from 'FAISS Vector database. Please help.

The way I import my FAISS Vector DB is like this below:
index = load_index_from_storage(storage_context=storage_context)

The RecursiveRetriever is looking below code, where I have no 'node_dict' from my vector import.

retriever_metadata = RecursiveRetriever(
    "vector",
    retriever_dict={"vector": vector_retriever_metadata},
    node_dict=all_nodes_dict,
    verbose=False,
)

The reference notebook I am following to build RecursiveRetriever is below:
