When does this happen?

IF FaissVectorStore.from_persist_dir fails because the persisted file is named 'default__vector_store.json' instead of 'vector_store.json'.

How others solved it

THEN Rename the file from 'default__vector_store.json' to 'vector_store.json' in the storage directory, or specify the correct path like `FaissVectorStore.from_persist_dir('./storage/default__vector_store.json')` (although that may still fail due to internal directory expectation; renaming is the confirmed workaround).

import os
os.rename("./storage/default__vector_store.json", "./storage/vector_store.json")
vector_store = FaissVectorStore.from_persist_dir("./storage")
