🔴 PRODUCTION CRITICAL FIX - Agent HTTP 422 Validation Error PROBLEM: - Production agents sending heartbeat with flat system_info fields - Backend Pydantic model was strict and rejecting unknown fields - Agents going offline with 'Validation error in request data' (HTTP 422) ROOT CAUSE: - Legacy agents embed system_info as flat key-value pairs in heartbeat JSON - Backend expected only defined fields, rejected extra fields - No backward compatibility for agent format variations SOLUTION - BACKEND ONLY (NO AGENT CHANGES): ✅ Added 'extra = "allow"' to AgentHeartbeat Pydantic Config ✅ Backend now accepts both formats: - Flat format: operating_system, kernel_version, etc. (legacy agents) - Nested format: system_info: {...} (future agents) ✅ Updated comments to clarify backward compatibility IMPACT: - ✅ ZERO CHANGES to production agent scripts - ✅ Existing agents will work immediately after backend deploy - ✅ Forward compatible with future agent upgrades - ✅ Tolerant to agent format variations SAFETY: - Minimal change (3 lines) - Pydantic still validates required fields - Extra fields ignored silently (no breaking changes) - Production agents continue without restart or upgrade DEPLOYMENT: 1. Deploy backend (this commit) 2. Agents come online automatically (no action needed) 3. Agent upgrades can happen later (when convenient) This fix ensures production stability without touching agent scripts.
