This is likely because you're using the "chat" wire API. We've announced that we are removing support for this older wire API at the end of this month, so it's unlikely that we will fix any bugs with it between now and then. Please switch to the "responses" wire API.

If this diagnosis isn't correct, let me know and I'll reopen the issue.
