AI Agents works in Version 1.99.1 but not in 1.108.2, Error Message shows Request Timeout Out

[Andrei_Oleniuc]

Hey everybody

I’ve been slowly getting back into n8n and I am happily surprised with how big it’s gotten and how good.

I’ve been playing around with the AI Agent and had a working prototype of my workflow in v1.99.1 but once I’ve updated to the newest Version the same workflow starts to not work anymore and always get’s stuck at the OpenAI Chat Model Node with Request Timeout Out.

I am not sure to what this could be related to. Appreciate any help in advance

Here is my workflow and the failed run:

Workflow:

Stack Trace:

NodeOperationError: Request timed out. at /usr/local/lib/node_modules/n8n/node_modules/.pnpm/@n8n+n8n-nodes-langchain@file+packages+@n8n+nodes-langchain_6a42402e1b434941076375196b5319e5/node_modules/@n8n/n8n-nodes-

Hii @Andrei_Oleniuc Hope You Are Well

I have try to fix the trouble facing in your workflow

I think you should update or recheck the credentials of open-ai for chat model & embedding model
I have tried with a open-router chat model & google gemini for embedding model .
I am sharing some screenshots that may find helpful .
