Error Signal
Error: Config validation failed: models.providers.kimi-coding.models.0.compat: Unrecognized key: "requiresOpenAiAnthropicToolPayload"What's Happening
You're hitting a configuration validation error in OpenClaw 3.8. Specifically, the openclaw configure command is trying to add an invalid key, requiresOpenAiAnthropicToolPayload, to your openclaw.json file, likely within the kimi-coding model's provider configuration. This breaks the configuration process.
The Fix
The quickest workaround is to manually edit your OpenClaw configuration file.
- Open
~/.openclaw/openclaw.jsonin your text editor. - Locate and delete the line containing
"requiresOpenAiAnthropicToolPayload": ...(the value doesn't matter, just remove the key-value pair). - Save the file.
- Restart your OpenClaw gateway:
openclaw gateway restart.
Alternatively, the clawaid tool can help diagnose and sometimes fix these issues. Run it with: npx clawaid.
Why This Occurs
This is a known regression in OpenClaw version 3.8. The openclaw configure wizard incorrectly introduces the requiresOpenAiAnthropicToolPayload key for certain model providers (like Kimi). This key is not recognized by the current configuration schema, causing validation to fail.
Prevention
Until a new OpenClaw version is released that fixes this bug, avoid using the interactive openclaw configure wizard if you suspect it might introduce this key. You can manually configure models using the command line:
openclaw models set kimi-coding/k2p5
Always check the GitHub issue tracker for updates on the official fix. Running npx clawaid after configuration changes can also help catch these issues early.
