Hello 👋 ! I'm trying to persist a Weaviate vector store to an S3 bucket, but I don't seem to be able to store the actual vector_store.json file. It's generating the docstore.json, graph_store.json, and index_store.json files, but no vector store. Any idea why that's happening? I've used this with the standard llama_index vector store without any issues. The code is pretty simple:
index = VectorStoreIndex.from_documents(documents, storage_context=storage_context, service_context=service_context)
index.storage_context.persist(persist_dir=f"embeddings/{directory}/weaviate/{embedding_model}/{embedding_mode}", fs=self.s3fs)
