Hi everyone,

I’m encountering an issue while working on the Agentic Retrieval Pipeline Example.

I have followed all the steps and executed the code as mentioned. The chat agent is successfully created in the Azure portal, but whenever I try giving a prompt through VS Code, I receive Bad Request error WhatsApp Image 2026-02-14 at 11.00.41 AM

I am attaching more screenshots from my project as well, you can refer to these images

Thanks in advance!
