Describe the problem/error/question

I am using an AI Agent connected to openai/gpt-4o-mini-search-preview model to conduct a competitor research but, I am running into an issue I have no idea how to solve.

Check below.

What is the error message (if any)?

Error in sub-node ‘OpenAI Chat Model‘

Does gpt-4o-mini-search-preview support tool calls, I’m assuming not.

I don´t have it connected to the tool endpoint just to the chat model.

I don´t know, I don´t understand.
