What is the expected behavior?

running codex in full auto with gemini provider, looking for a standard back and fourth file creation, management, editing, etc.

What do you see instead?

on running gemini models, sometimes they work, other times they will error and crash out, on asking things like what is this file, create a template index.html, hello, etc. models tested 1.5, 2.0 flash, 2.5, etc.

debug shows this error when it crashes on any of the models:
