• The error occurs specifically with Google models

TL;DR

The most likely fix is to check the compatibility of the Google API with OpenClaw version 2026.4.21 and potentially revert to a previous version of OpenClaw or wait for a patch.

Guidance

• Verify that the Google API key is correctly formatted and valid for the upgraded OpenClaw version.
• Check the OpenClaw documentation for any changes in Google API integration or requirements in version 2026.4.21.
• Test other Google models to see if the issue is specific to the gemma-4-31b-it model or a broader Google API compatibility problem.
• Consider reverting to the previous OpenClaw version to confirm if the issue is indeed caused by the upgrade.

Example

No code snippet is provided as the issue seems related to configuration and compatibility rather than code.

Notes

The issue might be due to changes in the Google API or OpenClaw's integration with it, introduced in version 2026.4.21. Without more specific details on the changes made in this version, it's challenging to provide a definitive fix.

Recommendation

Apply workaround: Revert to the previous version of OpenClaw until a compatible version with the Google API is released, as this is the most straightforward way to restore functionality without waiting for a potential patch.
