Weird HTTP 400 error on local Langgraph graph.

[dhruvbhrdwj]

I had been trying to create a new agent, for handling the research and drafting for my use case. I started noticing this weird change and error with my exisiting agents that are currently in production. I have tried everything, from upgrading langgraph, pydantic etc. Have even tried with a simple agent to check if the flow is flawed or not. Would really appreciate some help on this.
