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.
