Value Error With Faiss Index

[debuggedcoder]

I am having following error while using haystack. I have looked for solution but couldn't get any.

ValueError Traceback (most recent call last)
in ()
1 # Initialize FAISS document store.
2 # Set return_embedding to True, so generator doesn't have to perform re-embedding
----> 3 document_store = FAISSDocumentStore(faiss_index_factory_str="Flat", return_embedding=True)
4
5 # Initialize DPR Retriever to encode documents, encode question and query documents

ValueError: The number of documents present in the SQL database (999) does not match the number of embeddings in FAISS (0). Make sure your FAISS configuration file correctly points to the same database that was used when creating the original index.
