THEN Rename the persisted file from default__vector_store.json to vector_store.json in the storage directory, or ensure that both persist and load use the same naming convention. This mismatch occurs because newer LlamaIndex versions add a namespace prefix to vector store filenames.

# Workaround: rename the file
import os
os.rename('./storage/default__vector_store.json', './storage/vector_store.json')
vector_store = FaissVectorStore.from_persist_dir('./storage')
