PR fix notes

PR #17441: fix(transport): omit thinking_config for Gemma on the gemini provider (#17426)

Description (problem / solution / changelog)

Summary

  • Hermes was sending extra_body.thinking_config for every chat call routed through the gemini provider — including Gemma (gemma-4-31b-it), PaLM, and any other non-Gemini Google model on the same endpoint
  • Those models reject the field at the API edge: HTTP 400 — Unknown name \"thinking_config\": Cannot find field
  • Result: Gemma users on the gemini provider exit immediately on every chat (#17426)

The bug

chat_completions.py:365-368 builds thinking_config whenever provider_name in {\"gemini\", \"google-gemini-cli\"}:

```python if provider_name in {"gemini", "google-gemini-cli"}: thinking_config = _build_gemini_thinking_config(model, reasoning_config) if thinking_config: extra_body["thinking_config"] = thinking_config ```

The helper unconditionally returned a dict — never None — for any model under those providers. So extra_body[\"thinking_config\"] was always set, including for Gemma. The Gemini API's strict request validator rejects unknown fields, even the polite {\"includeThoughts\": False} shape.

The reporter's payload:

``` provider: gemini model: gemma-4-31b-it → HTTP 400: 'Invalid JSON payload received. Unknown name "thinking_config": Cannot find field.' ```

The fix

_build_gemini_thinking_config() now mirrors the same family-detection pattern it already uses for Gemini-2.5 vs Gemini-3 clamping: normalise the model id, strip an OpenRouter-style google/ prefix, and short-circuit to None when the result doesn't start with gemini.

We return None rather than {\"includeThoughts\": False} because the API rejects the field name itself — there is no "off" shape that's safe.

The Gemini guard fires after the google/ strip, so:

  • gemini-2.5-flash → still gets thinking_config
  • gemini-3-flash-preview → still gets thinking_config
  • google/gemini-3.1-pro-preview → still gets thinking_config (existing behaviour preserved)
  • gemma-4-31b-it → no thinking_config
  • google/gemma-4-31b-it → no thinking_config

Test plan

  • Focused regression: 3 new cases in tests/agent/transports/test_chat_completions.py:
    • test_gemma_does_not_receive_thinking_config — reasoning enabled, high effort → field absent
    • test_gemma_disabled_reasoning_still_omits_thinking_config — enabled: False → field absent (proves the omit-not-disable contract)
    • test_google_prefixed_gemma_also_omits_thinking_config — OpenRouter-style id → field absent
  • Adjacent suite: existing 5 Gemini cases (`test_gemini_reasoning`, `test_gemini_25_`, `test_gemini_pro_`, etc.) all still pass — the new guard only kicks in for non-Gemini models
  • Regression guard: stashing the chat_completions.py change makes both Gemma tests fail at `assert "thinking_config" not in kw.get("extra_body", {})` (the field is present); restoring the fix flips them back to passing
  • Full file run: `pytest tests/agent/transports/test_chat_completions.py` → 57 passed

TL;DR

The most likely fix is to remove or update the "thinking_config" field from the JSON payload to match the expected fields by the Google API.

Guidance

  • Review the code that constructs the JSON payload sent to the Google API to identify where the "thinking_config" field is being added.
  • Check the Google API documentation to confirm the expected fields for the JSON payload.
  • Update the code to remove or rename the "thinking_config" field to match the expected fields.
  • Verify that the updated code constructs a valid JSON payload that can be successfully processed by the Google API.

Example

No code snippet is provided as the issue does not include the relevant code. However, the fix will involve updating the code that constructs the JSON payload to remove or update the "thinking_config" field.

Notes

The exact fix will depend on the specific code that constructs the JSON payload and the expected fields for the Google API. Additional debugging may be necessary to identify the root cause of the issue.

Recommendation

Apply workaround: Remove or update the "thinking_config" field from the JSON payload to match the expected fields by the Google API. This should resolve the "Invalid JSON payload received" error and allow the API request to succeed.
