+# N8N Master Loop Discord Summary Node Missing URL
+
+## Problem
+The "Server Health Monitor - Master Loop" workflow (ID: `p7XmW23SgCs3hEkY`) was failing 10/10 executions with `WorkflowHasIssuesError`. The failure was silent — health checks appeared to be running fine through the sub-workflow, masking the root cause.
+
+## Root Cause
+The Discord Summary `httpRequest` node had no URL configured. The node only fires when `has_escalations=true`, so routine health checks (sub-workflow) succeeded while the master loop consistently errored without obvious symptoms.
+
+## Fix
+Added to the Discord Summary httpRequest node:
+- `method`: `POST`
+- `url`: `https://discord.com/api/webhooks/1451783909409816763/O9PMDiNt6ZIWRf8HKocIZ_E4vMGV_lEwq50aAiZ9HVFR2UGwO6J1N9_wOm82p0MetIqT`
+
+## Key Insight
+When a workflow has conditional paths (escalation-only Discord notify), the error branch may never execute during normal operation — making a misconfigured node invisible until an escalation actually occurs. Always validate all paths in a workflow, not just the happy path.
