openclaw - 💡(How to fix) Fix [Bug]: LLM request failed: provider rejected the request schema or tool payload. [1 comments, 2 participants]

Bug type

Regression (worked before, now fails)

Beta release blocker

No

Summary

The AI agent keeps failing with the following error on every message:

LLM request failed: provider rejected the request schema or tool payload

Reproduction

1. Open the AI agent
2. Send a prompt
3. Observe the failure response

I'm using copilot models

Steps to reproduce

Integrate/configure AI in OpenClaw. Open the web UI and send a normal message to the agent. Observe the failed/error response. Send a normal message through the WhatsApp integration. Observe the same failed/error response there as well.

Expected behavior

Prior reports in the OpenClaw issue tracker describe the same failure mode, where normal agent prompts should be accepted and processed without returning LLM request failed: provider rejected the request schema or tool payload. Related reports indicate expected behavior is that OpenClaw should normalize and send a provider-compatible request/tool payload so ordinary prompts complete successfully instead of failing with schema or tool-payload rejection.

Actual behavior

AI agent normal prompt’larda başarısız oluyor ve yanıt üretmek yerine kullanıcıya görünen LLM request failed: provider rejected the request schema or tool payload hatasını döndürüyor.
