openclaw - 💡(How to fix) Fix [Bug] 404 Model Not Found when spawning sub-agents with google/gemini-3.1-flash-lite-preview [1 comments, 2 participants]

• Description: Using google/gemini-3.1-flash-lite-preview works fine in the main session, but spawning sub-agents or resetting the session results in a 404 status code (no body) error.

TL;DR

The issue may be resolved by ensuring the models/ prefix is correctly included in the request to the Google Generative AI API.

Guidance

• Verify that the models/ prefix is being stripped or overwritten in the transport layer by inspecting the actual request sent to the API.
• Check the OpenClaw v2026.4.23 documentation to see if there are any configuration options or settings that can be adjusted to preserve the models/ prefix.
• Consider modifying the code to log or debug the request URL before it is sent to the API to confirm the prefix is being included.
• Review the google/gemini-3.1-flash-lite-preview documentation to ensure that the models/ prefix is required for all API requests, including those from sub-agents or reset sessions.

Notes

The issue may be specific to the OpenClaw version or the Windows 10 environment, and further investigation may be needed to determine the root cause.

Recommendation

Apply a workaround to manually include the models/ prefix in the request URL, as the attempted fix in provider-model-id-normalize.js was unsuccessful.
