### Steps to reproduce

1. Configure azure-openai-responses provider with a reasoning model
2. Start a multi-turn conversation (3+ turns)
3. Error appears on subsequent turns

### Expected behavior

Setting "reasoning": false stops the error but disables thinking.

### Actual behavior

Using `azure-openai-responses` provider with `gpt-5.3-codex` (reasoning model).
After a few turns, agent fails with:
