Quick Start Guide

Step 1: Run the Migration

# Connect to your database
psql -U postgres -d pulse

# Run migration 036
\i /opt/stacks/pulse/migrations/036_create_ticket_workflow_tables.sql

# Verify tables created
\dt ticket_workflow*

# Expected output:
# - ticket_workflows
# - ticket_workflow_steps
# - ticket_workflow_executions
# - ticket_workflow_execution_steps

Step 2: Verify Seed Data

-- Check "Ticket Triage" workflow was seeded
SELECT id, name, is_active, trigger_event FROM ticket_workflows;

-- Check workflow steps (should have 11 steps)
SELECT step_order, step_type, name, is_active
FROM ticket_workflow_steps
WHERE workflow_id = 1
ORDER BY step_order;

Expected steps:

  1. Branch Routing (classify)
  2. Ticket Type (classify)
  3. Issue Classification (classify)
  4. Priority (classify)
  5. Queue Routing (classify)
  6. Validate Classification (validate)
  7. AI Classification (ai_classify) — conditional
  8. AI Title Cleanup (ai_title) — conditional
  9. Delay Before Update (delay)
  10. Update Autotask Ticket (update_ticket)
  11. Generate Troubleshooting Steps (ai_troubleshooting) — conditional

Step 3: Start the Application

# Navigate to project directory
cd /opt/stacks/pulse

# Install dependencies (if needed)
npm install

# Start development server
npm run dev

# Build for production
npm run build
npm start

Step 4: Access the Admin UI

Navigate to: http://localhost:3000/admin/workflow

You should see:

  • Master Control card at top (currently disabled)
  • Ticket Triage workflow card (seeded from migration)
  • Quick links to Classification Rules, AI Templates, Settings

Testing Checklist

Database Testing

  • Migration 036 runs without errors
  • All 4 tables created with correct schema

Workflow Engine Testing

Create Test Ticket:

Option A: Use Autotask webhook simulator Option B: Create ticket directly in database

-- Create a test ticket
INSERT INTO tickets (
  id, ticket_number, title, description,
  ticket_category, company_id, status, created_at
) VALUES (
  999999, 'T2026-TEST-001',
  'Test ticket for workflow engine',
  'This is a test ticket to verify the workflow engine',
  3, -- NOC category (eligible for triage)
  29682833, -- valid company_id
  1, -- New
  NOW()
);

Trigger Workflow Manually:

// In Node.js console or API route
import { ticketWorkflowEngine } from '@/lib/services/ticket-workflow-engine';

const ticket = {
  id: 999999,
  ticket_number: 'T2026-TEST-001',
  title: 'Test ticket for workflow engine',
  description: 'This is a test ticket',
  ticket_category: 3,
  ticket_type: null,
  priority: null,
  queue_id: null,
  issue_type: null,
  sub_issue_type: null,
  company_id: 29682833,
  // ... other fields
};

await ticketWorkflowEngine.processTrigger('ticket.created', ticket);

Verify Execution:

-- Check execution record
SELECT * FROM ticket_workflow_executions WHERE ticket_id = 999999;

-- Check execution steps
SELECT
  step_order, step_type, step_name, status, duration_ms,
  error_message, output_data
FROM ticket_workflow_execution_steps
WHERE execution_id = (
  SELECT id FROM ticket_workflow_executions WHERE ticket_id = 999999
)
ORDER BY step_order;

-- Check field changes
SELECT context, field_changes
FROM ticket_workflow_executions
WHERE ticket_id = 999999;

Integration Testing

Webhook Flow:

  1. Enable master switch in UI (/admin/workflow)
  2. Enable "Ticket Triage" workflow
  3. Create ticket via Autotask webhook
  4. Verify execution in database
  5. Check Autotask ticket for updates

Dry-Run Testing:

  1. Select recent ticket in Test tab
  2. Run dry-run
  3. Verify proposed changes shown
  4. Verify no actual Autotask update made

Comparison with Old Engine:

  1. Run 100 tickets through old engine (keep results)
  2. Run same 100 tickets through new engine (dry-run)
  3. Compare classifications
  4. Expect >99% match rate

Deployment Plan

Phase 1: Staging Deployment (Current)

  1. Deploy Backend:

    • Run migration 036
    • Deploy updated code
    • Verify services start without errors
  2. Smoke Test:

    • Access admin UI
    • Verify workflow list loads
    • Verify workflow editor loads
    • Test dry-run endpoint
  3. Functional Test:

    • Create test ticket
    • Trigger workflow manually
    • Verify execution in database
    • Check for errors
  4. Parallel Run:

    • Keep old engine enabled (commented line in webhook-service.ts)
    • Enable new engine
    • Compare results for 3-7 days
    • Monitor for discrepancies

Phase 2: Production Deployment

Prerequisites:

  • Staging tests pass (>99% match with old engine)
  • No errors in execution logs
  • Performance acceptable (<1s avg execution time)
  • Admin UI stable and functional

Deployment Steps:

  1. Run migration 036 in production
  2. Deploy code (new engine runs alongside old)
  3. Monitor for 7 days
  4. If successful, disable old engine
  5. Monitor for another 7 days

Rollback Plan:

  • Disable master switch in admin UI (immediate)
  • Comment out ticketWorkflowEngine.processTrigger() in webhook-service.ts
  • Uncomment old workflowEngine.process() call
  • Redeploy

Phase 3: Deprecation (After 30 days)

  • Mark old workflow-engine.ts as deprecated
  • Archive old workflow_executions and workflow_execution_steps tables
  • Remove old engine code after 6 months
  • Remove old tables after 1 year (with backup)

Troubleshooting

Migration Fails

Error: "relation already exists"

  • Tables may exist from previous attempt
  • Check: SELECT * FROM ticket_workflows;
  • Solution: Drop tables and re-run, or use IF NOT EXISTS pattern (already in migration)

Error: "column does not exist"

  • Check table schema matches migration
  • Verify no column name typos

API Returns 500 Error

Check server logs:

# Development
npm run dev
# Look for [API] errors in console

# Production
pm2 logs pulse

Common issues:

  • Database connection failed → Check DATABASE_URL
  • Missing import → Check file paths and exports
  • Type mismatch → Check TypeScript types

Workflow Not Executing

Check master switch:

SELECT key, value FROM workflow_settings WHERE key = 'workflow_engine_enabled';

Check workflow is active:

SELECT id, name, is_active FROM ticket_workflows WHERE id = 1;

Check trigger conditions:

  • Verify ticket matches trigger_conditions
  • Check ticket.ticket_category is in [2, 3, 159, 161]
  • Check ticket.creator_resource_id not in exclusion list

Check logs:

# Look for [TICKET-WORKFLOW] messages
grep -i "ticket-workflow" logs/*.log

Steps Not Executing

Check step is active:

SELECT step_order, name, is_active FROM ticket_workflow_steps WHERE workflow_id = 1;

Check step condition:

  • If step has condition, verify it evaluates to true
  • Check context has required fields

Check for errors:

SELECT step_order, step_name, status, error_message
FROM ticket_workflow_execution_steps
WHERE execution_id = ?;

Performance Metrics

Target Performance:

  • Workflow execution: <1s for robotic classification
  • Workflow execution: <3s for hybrid (with AI)
  • API response time: <500ms for list endpoints
  • Admin UI load time: <2s

Monitoring Queries:

-- Average execution time
SELECT
  AVG(duration_ms) as avg_ms,
  MAX(duration_ms) as max_ms,
  MIN(duration_ms) as min_ms
FROM ticket_workflow_executions
WHERE created_at > NOW() - INTERVAL '24 hours';

-- Success rate
SELECT
  status,
  COUNT(*) as count,
  ROUND(COUNT(*) * 100.0 / SUM(COUNT(*)) OVER (), 2) as percentage
FROM ticket_workflow_executions
WHERE created_at > NOW() - INTERVAL '24 hours'
GROUP BY status;

-- Classification method breakdown
SELECT
  classification_method,
  COUNT(*) as count
FROM ticket_workflow_executions
WHERE created_at > NOW() - INTERVAL '24 hours'
  AND status = 'completed'
GROUP BY classification_method;
