Aiwf:error Tracking

your project Sentry Integration Skill

Purpose

This skill enforces comprehensive Sentry error tracking and performance monitoring across all your project services following Sentry v8 patterns.

When to Use This Skill

• Adding error handling to any code
• Creating new controllers or routes
• Instrumenting cron jobs
• Tracking database performance
• Adding performance spans
• Handling workflow errors

🚨 CRITICAL RULE

ALL ERRORS MUST BE CAPTURED TO SENTRY - No exceptions. Never use console.error alone.

Current Status

Form Service ✅ Complete

• Sentry v8 fully integrated
• All workflow errors tracked
• SystemActionQueueProcessor instrumented
• Test endpoints available

Email Service 🟡 In Progress

• Phase 1-2 complete (6/22 tasks)
• 189 ErrorLogger.log() calls remaining

Sentry Integration Patterns

1. Controller Error Handling

// ✅ CORRECT - Use BaseController
import { BaseController } from '../controllers/BaseController';

export class MyController extends BaseController {
    async myMethod() {
        try {
            // ... your code
        } catch (error) {
            this.handleError(error, 'myMethod'); // Automatically sends to Sentry
        }
    }
}

2. Route Error Handling (Without BaseController)

import * as Sentry from '@sentry/node';

router.get('/route', async (req, res) => {
    try {
        // ... your code
    } catch (error) {
        Sentry.captureException(error, {
            tags: { route: '/route', method: 'GET' },
            extra: { userId: req.user?.id }
        });
        res.status(500).json({ error: 'Internal server error' });
    }
});

3. Workflow Error Handling

import { WorkflowSentryHelper } from '../workflow/utils/sentryHelper';

// ✅ CORRECT - Use WorkflowSentryHelper
WorkflowSentryHelper.captureWorkflowError(error, {
    workflowCode: 'DHS_CLOSEOUT',
    instanceId: 123,
    stepId: 456,
    userId: 'user-123',
    operation: 'stepCompletion',
    metadata: { additionalInfo: 'value' }
});

4. Cron Jobs (MANDATORY Pattern)

#!/usr/bin/env node
// FIRST LINE after shebang - CRITICAL!
import '../instrument';
import * as Sentry from '@sentry/node';

async function main() {
    return await Sentry.startSpan({
        name: 'cron.job-name',
        op: 'cron',
        attributes: {
            'cron.job': 'job-name',
            'cron.startTime': new Date().toISOString(),
        }
    }, async () => {
        try {
            // Your cron job logic
        } catch (error) {
            Sentry.captureException(error, {
                tags: {
                    'cron.job': 'job-name',
                    'error.type': 'execution_error'
                }
            });
            console.error('[Job] Error:', error);
            process.exit(1);
        }
    });
}

main()
    .then(() => {
        console.log('[Job] Completed successfully');
        process.exit(0);
    })
    .catch((error) => {
        console.error('[Job] Fatal error:', error);
        process.exit(1);
    });

5. Database Performance Monitoring

import { DatabasePerformanceMonitor } from '../utils/databasePerformance';

// ✅ CORRECT - Wrap database operations
const result = await DatabasePerformanceMonitor.withPerformanceTracking(
    'findMany',
    'UserProfile',
    async () => {
        return await PrismaService.main.userProfile.findMany({
            take: 5,
        });
    }
);

6. Async Operations with Spans

import * as Sentry from '@sentry/node';

const result = await Sentry.startSpan({
    name: 'operation.name',
    op: 'operation.type',
    attributes: {
        'custom.attribute': 'value'
    }
}, async () => {
    // Your async operation
    return await someAsyncOperation();
});

Error Levels

Use appropriate severity levels:

• fatal: System is unusable (database down, critical service failure)
• error: Operation failed, needs immediate attention
• warning: Recoverable issues, degraded performance
• info: Informational messages, successful operations
• debug: Detailed debugging information (dev only)

Required Context

import * as Sentry from '@sentry/node';

Sentry.withScope((scope) => {
    // ALWAYS include these if available
    scope.setUser({ id: userId });
    scope.setTag('service', 'form'); // or 'email', 'users', etc.
    scope.setTag('environment', process.env.NODE_ENV);

    // Add operation-specific context
    scope.setContext('operation', {
        type: 'workflow.start',
        workflowCode: 'DHS_CLOSEOUT',
        entityId: 123
    });

    Sentry.captureException(error);
});

Service-Specific Integration

Form Service

Location: ./blog-api/src/instrument.ts

import * as Sentry from '@sentry/node';
import { nodeProfilingIntegration } from '@sentry/profiling-node';

Sentry.init({
    dsn: process.env.SENTRY_DSN,
    environment: process.env.NODE_ENV || 'development',
    integrations: [
        nodeProfilingIntegration(),
    ],
    tracesSampleRate: 0.1,
    profilesSampleRate: 0.1,
});

Key Helpers:

• WorkflowSentryHelper - Workflow-specific errors
• DatabasePerformanceMonitor - DB query tracking
• BaseController - Controller error handling

Email Service

Location: ./notifications/src/instrument.ts

import * as Sentry from '@sentry/node';
import { nodeProfilingIntegration } from '@sentry/profiling-node';

Sentry.init({
    dsn: process.env.SENTRY_DSN,
    environment: process.env.NODE_ENV || 'development',
    integrations: [
        nodeProfilingIntegration(),
    ],
    tracesSampleRate: 0.1,
    profilesSampleRate: 0.1,
});

Key Helpers:

• EmailSentryHelper - Email-specific errors
• BaseController - Controller error handling

Configuration (config.ini)

[sentry]
dsn = your-sentry-dsn
environment = development
tracesSampleRate = 0.1
profilesSampleRate = 0.1

[databaseMonitoring]
enableDbTracing = true
slowQueryThreshold = 100
logDbQueries = false
dbErrorCapture = true
enableN1Detection = true

Performance Monitoring

Requirements

1. All API endpoints must have transaction tracking
2. Database queries > 100ms are automatically flagged
3. N+1 queries are detected and reported
4. Cron jobs must track execution time

Transaction Tracking

import * as Sentry from '@sentry/node';

// Automatic transaction tracking for Express routes
app.use(Sentry.Handlers.requestHandler());
app.use(Sentry.Handlers.tracingHandler());

// Manual transaction for custom operations
const transaction = Sentry.startTransaction({
    op: 'operation.type',
    name: 'Operation Name',
});

try {
    // Your operation
} finally {
    transaction.finish();
}

Common Mistakes to Avoid

❌ NEVER use console.error without Sentry ❌ NEVER swallow errors silently ❌ NEVER expose sensitive data in error context ❌ NEVER use generic error messages without context ❌ NEVER skip error handling in async operations ❌ NEVER forget to import instrument.ts as first line in cron jobs

Implementation Checklist

When adding Sentry to new code:

• Imported Sentry or appropriate helper
• All try/catch blocks capture to Sentry
• Added meaningful context to errors
• Used appropriate error level
• No sensitive data in error messages
• Added performance tracking for slow operations
• Tested error handling paths
• For cron jobs: instrument.ts imported first
