Hi @0ne ,

Good to see you back!

Could you please share your workflow so we can see how you’re setting it?
What chat model are you using? Is it giving you issues with all the Agents or only some?

It’s a little abstract so far and it makes it hard to debug

Have you tried using the tools agent rather than the conversational agent?

It looks this is a bug when using the o1-preview model. I’ve reported this internally

sirdavidoff · November 1, 2024, 10:16am

Actually the o1-preview model doesn’t yet support tool calling and so isn’t compatible with the agent node
