vector_db.json in vector_db_interface should be db.json

[eingrid]

  with weaviate.connect_to_local(host=host, port=port) as client:
        while not client.is_ready():
            pass
        if not client.collections.exists("KnowledgeBase"):
            schema = json.load(open("vector_db.json"))
            client.collections.create_from_dict(schema)

        if not client.collections.exists("ProductList") and os.path.exists("db.json"):
            schema = json.load(open("db.json"))
            client.collections.create_from_dict(schema)

This should be fixed
