Error message when running the LangChain integration demo

Describe the bug
Using the langgraph code from this page: https://docs.chainlit.io/integrations/langchain

It works but the following line is spammed more than a 100 times in the terminal where I run the app:

To Reproduce
Steps to reproduce the behavior:

1. Follow the demo instructions. I used uv to run the script

Expected behavior
The starting code shared should be sane, with clean logs, no spammed of warning. And if you have to send a warning send it once ideally

Desktop (please complete the following information):
