Bug: No module named 'dataiku.core.vector_stores.lifecycle

I followed your document here: https://developer.dataiku.com/latest/tutorials/genai/nlp/create-knowledge-bank/index.html#wrapping-up.

I try to query the KB.
With this line: vector_store = kb_core.as_langchain_vectorstore()
I got error:

from dataiku.core.vector_stores.lifecycle.shared_folder import (
ModuleNotFoundError: No module named 'dataiku.core.vector_stores.lifecycle'

Look the code I did not find this module named lifecyle in vector_stores. This should be a bug.
And I did not find this module anywhere in the dataiku module.

从教程的“Wrapping up”部分开始，并重现 kb_core.as_langchain_vectorstore()。检查 dataiku.core.vector_stores 包和失败的 lifecycle.shared_folder 导入，然后确定为什么文档中的查询找不到该模块。完成的标准是文档中的查询能够在没有 ModuleNotFoundError 的情况下正常运行，或者文档明确指出所需的包和版本。
