Using Langgraph with Vertex AI Reasoning Engine: Any Experience?

[emerworth]

Hi everyone!!

I'm currently working on a project where I've been using LangchainAgent from Reasoning Engine docs. Now I am trying to make my custom Agent class using Langgraph, I managed to get the class working in my local environment, and I also managed to deploy the Reasoning Engine. But when I try to use the deployed RE, it ends up having an error (probably in the set_up method, called in query method like template does). Has anyone tried using the reasoning engine with Langgraph?

Thanks in advance!

Have you tried looking at the published LangGraph example notebook on GitHub?

Thanks for commenting, I hadn't seen it. I made the post two months ago and at that time I created my own custom class to deploy Langgraph in the reasoning engine service. It's done in a very similar way, which makes me happy!

Thank you!
