Gemeni and other model not working in Agent Mode

Bug Reports

Describe the Bug

when I try to use Genemi 2.5 pro in Agent mode I get this error (at the bottom of this message).
When I use it in Ask mode it works fine.
I also have the same issue for other models like deepseek v 3.1 or Grok 4 (well with grok 4 I don’t even have any error message, just nothing is done).

Is it expected ?

Thanks.
