[Bug]: App startup error when trying to initialize GPTCache with Redis and Weaviate

Current Behavior

Seeing the following error when trying to initialize GPTCache with redis as the base cache and weaviate as the vector store

2023-10-30 16:29:24,502 - 139826724846464 - weaviate.py-weaviate:67 - WARNING: The GPTCache collection already exists, and it will be used directly. main function failed error: unknown command 'FT.SEARCH', with args beginning with: 'gptcache:questions:index' '@deleted:[0 0]' 'LIMIT' '0' '1000' , stack trace: Traceback (most recent call last):

Expected Behavior

Would not expect to see this error from the weaviate implementation on cache initialization

Steps To Reproduce

Initialize GPT Cache as such:

Data manager

        # Init Redis cache store
        cache_store = GPTCacheBase(
            name='redis',
            redis_host=redis_host,
            redis_port=redis_port,
            global_key_prefix="gptcache",
        )

        # Init Weaviate DB
        auth_config = weaviate.AuthApiKey(api_key=weaviate_api_key)
        vector_base = VectorBase(
            name="weaviate",
            url=weaviate_url,
            auth_client_secret=auth_config,
        )

        data_manager = get_data_manager(
            cache_base=cache_store,
            vector_base=vector_base,
            max_size=100,
            eviction='LRU',
        )

Cache config:

        cache.init(
            embedding_func=OpenAI(api_key=openai_key),
            data_manager=data_manager,
            similarity_evaluation=SearchDistanceEvaluation(max_distance=1)
        )
