Error Message and Stack Trace (if applicable)

There's no server side stack trace, no error. It's only in the UI.

Description

Hi,

I started getting today a "Failed to render conversation" error in a locally deployed server based off https://langchain-ai.github.io/langgraph/tutorials/langgraph-platform/local-server/

The line below states:
Error: fetchStateHistory must be set to true to use history

Only the Chat tab errors, the Graph tab works.

also just ran into this issue

UPDATE:
Not sure if this will help but i rolled back langsmith-api to 0.4.37 as well as made my default browser chrome (had seen some issues in the past using Dia for some odd reason).

It appears to be working normally for me

The issue now "went away" with my same configuration;
I assume the remote code at smith.langchain.com has been updated/fixed.
