Debugging OpenClaw in April 2026: Did GitHub Brake Your AI Agent Setup
Posted: April 23, 2026 | A real-world troubleshooting journey with OpenClaw, Claude models, and GitHub Copilot changes.
What Happened
Did you wake up to a broken OpenClaw installation. The gateway service wouldn’t restart properly, and worse — every agent request was failing with:
LLM request failed: provider rejected the request schema or tool payload.
After debugging, the root cause became crystal clear.
Key Lessons Learned
1. GitHub Copilot Model Changes (April 2026)
GitHub quietly removed or restricted several high-end Claude models from individual Copilot plans:
- claude-opus-4.5 / 4.6 → completely gone
- claude-sonnet-4.5 → no longer supported on most plans
- Only claude-haiku-4.5 and lighter GPT models remain reliably available
Even upgrading to Copilot Pro+ only gives you Opus 4.7 with a painful 7.5× multiplier. Not worth it for heavy agent use.
2. Direct Anthropic API Key is the Winning Strategy
The most reliable setup for OpenClaw right now:
| Model | Quality | Speed | Est. Monthly Cost (Heavy Use) | Recommendation |
|---|---|---|---|---|
| anthropic/claude-sonnet-4.6 | Excellent (very close to Opus) | Fast | $60–120 | Best daily driver |
| anthropic/claude-opus-4.7 | Best | Slower | $100–250+ | Only for hard tasks |
| claude-haiku-4.5 (via Copilot) | Noticeably weaker | Very fast | $15–60 | Light use only |
3. How to Properly Add an Anthropic Key to OpenClaw
Don’t put it in openclaw.json (it rejects the providers key now).
Correct method:
# 1. Add to systemd service
mkdir -p ~/.config/systemd/user/openclaw-gateway.service.d
cat > ~/.config/systemd/user/openclaw-gateway.service.d/env.conf <
4. Force the Correct Model (The Stubborn Part)
Even after setting the model, the main Telegram agent kept falling back to the broken GitHub Copilot version. Final working commands:
openclaw models set anthropic/claude-sonnet-4.6
openclaw config set agents.defaults.model.primary "anthropic/claude-sonnet-4.6"
openclaw config set agents.defaults.model.fallbacks ["openai/gpt-5.4"]
openclaw gateway restart
Final Recommended Setup (April 2026)
Primary: anthropic/claude-sonnet-4.6 (direct API key)
Fallback: openai/gpt-5.4
Avoid: Any github-copilot/claude-* models for now
GitHub’s sudden model restrictions in April 2026 broke a lot of agent setups. The cleanest, most future-proof cloud path is:
Direct Anthropic API key + Sonnet 4.6 as primary.
Hope this saves someone else a few hours of debugging. 🦞
