fixed with threadr_chat_vector._driver.close() -- didn't see that in any documentations or examples..

Hello and thanks for reaching out. Great to hear you managed to figure out that you need to close the driver.

It is actually documented: https://neo4j.com/docs/api/python-driver/current/api.html#neo4j.GraphDatabase The first 2 examples of using the driver in the API docs show how to either close it using a call to .close(), or better yet, how to use the driver as a context manager using the with keyword.

I'm following along with lessons in the neo4j academy and I don't think it was mentioned how to do it through the langchain wrapper.
