Sentry Error Manager

⚠️ MANDATORY: Document Every Fix on Sentry

Every Sentry issue that is addressed or fixed MUST be documented with a comment on Sentry itself. This is non-negotiable.

Required Checklist (ALL items MUST be completed)

For EVERY Sentry issue you fix, you MUST complete ALL of these steps:

• 1. Fix the code and commit with Sentry issue reference
• 2. Add a comment to the Sentry issue documenting:
  • Commit hash
  • Files changed
  • Description of the fix
  • Date
• 3. Update issue status (resolve if fix is deployed and verified)
• 4. Verify comment was added (look for success message with comment ID)

Command to Add Comment (REQUIRED)

Copy# REQUIRED after every fix - DO NOT SKIP
./.claude/skills/sentry-error-manager/scripts/sentry.sh comment <issue_id> "🔧 FIX DEPLOYED - $(date +%Y-%m-%d)

Commit: <hash>
File: <path>
Change: <description>

Monitoring for recurrence."

Failure to Comment = Incomplete Work

A fix is NOT complete until:

1. The code fix is committed and pushed
2. A comment exists on the Sentry issue (verified by success message)
3. The issue status is updated

If you fix code but forget to comment on Sentry, the task is NOT done. Go back and add the comment before proceeding.

When to Use This Skill

Use this skill when:

• Fetching and reviewing Sentry errors
• Resolving, ignoring, or assigning issues
• Adding comments to track investigation progress
• Weekly error reviews and post-deployment verification

Primary Tool: Shell Script

Location: .claude/skills/sentry-error-manager/scripts/sentry.sh

This is the only tool you need for all Sentry operations. It auto-loads .env.local for authentication.

Quick Start

Copy# View all unresolved issues
./.claude/skills/sentry-error-manager/scripts/sentry.sh list

# Get details for specific issue
./.claude/skills/sentry-error-manager/scripts/sentry.sh get 7034568465 --events

# Add comment to track progress
./.claude/skills/sentry-error-manager/scripts/sentry.sh comment 7034568465 "🔍 INVESTIGATING"

# Resolve after 3+ days zero recurrence
./.claude/skills/sentry-error-manager/scripts/sentry.sh resolve 7034568465

All Commands

Prerequisites

Environment: Token is loaded automatically from .env.local:

CopySENTRY_AUTH_TOKEN=sntryu_...

Get Token: https://sentry.io/settings/account/api/auth-tokens/

Required Scopes: event:read, event:write, event:admin, project:read, project:write

Resolution Workflow

Critical Rules

1. Wait 3+ days after fix deployment before resolving
2. Verify zero recurrence during that period
3. Add comments at each stage (investigating → fix deployed → resolved)
4. Monitor 7 days post-resolution for regression

Decision Tree

CopyIs fix deployed to production?
├─ NO → Wait for deployment
└─ YES → Has it been 3+ days since last event?
    ├─ NO → Wait longer
    └─ YES → ✅ Safe to resolve

Comment Templates

Copy# Start investigation
./.claude/skills/sentry-error-manager/scripts/sentry.sh comment <id> "🔍 INVESTIGATING - $(date +%Y-%m-%d)

Assigned to: Claude Code
Status: Analyzing root cause"

# Fix deployed
./.claude/skills/sentry-error-manager/scripts/sentry.sh comment <id> "🔧 FIX DEPLOYED - $(date +%Y-%m-%d)

Commit: <hash>
File: <path>
Change: <description>

Monitoring for recurrence."

# Resolve
./.claude/skills/sentry-error-manager/scripts/sentry.sh comment <id> "✅ RESOLVED - $(date +%Y-%m-%d)

Reason: 3+ days zero recurrence
Resolved by: Claude Code"

Common Workflows

Weekly Review

Copy# 1. List current issues
./.claude/skills/sentry-error-manager/scripts/sentry.sh list

# 2. Check each issue's last seen date
./.claude/skills/sentry-error-manager/scripts/sentry.sh get <id>

# 3. Resolve stale issues (7+ days no recurrence)
./.claude/skills/sentry-error-manager/scripts/sentry.sh resolve <id1> <id2>

Fix and Track

Copy# 1. Assign and comment
./.claude/skills/sentry-error-manager/scripts/sentry.sh assign 7034568465
./.claude/skills/sentry-error-manager/scripts/sentry.sh comment 7034568465 "🔍 INVESTIGATING - analyzing root cause"

# 2. Fix code, commit with Sentry link
git commit -m "fix: resolve error description

Fixes: https://ballee.sentry.io/issues/7034568465/"

# 3. Comment with fix details
./.claude/skills/sentry-error-manager/scripts/sentry.sh comment 7034568465 "🔧 FIX DEPLOYED - commit abc123"

# 4. Wait 3+ days, then resolve
./.claude/skills/sentry-error-manager/scripts/sentry.sh resolve 7034568465

Implementation Patterns

This section documents how Sentry is configured and integrated in the Ballee codebase.

Sentry Configuration Files

Error Boundary Hierarchy

Next.js uses error.tsx files to catch and handle errors at different route levels:

Copyapp/
├── error.tsx                    # Root fallback (catches all unhandled)
├── (auth)/error.tsx            # Auth routes
├── (marketing)/error.tsx       # Public marketing pages
├── admin/error.tsx             # Admin section root
│   ├── clients/error.tsx       # Client management
│   ├── events/error.tsx        # Event management
│   └── settings/error.tsx      # Settings
└── home/
    ├── (user)/error.tsx        # Personal account
    │   ├── inbox/error.tsx     # Inbox/chat
    │   └── events/error.tsx    # User events
    └── [account]/error.tsx     # Team account
        ├── events/error.tsx    # Team events
        └── settings/error.tsx  # Team settings

Error Boundary Coverage

Current coverage: ~17 error.tsx files across ~118 pages

Gaps: Some admin subsections rely on parent boundaries. Error propagates up until caught.

Adding New Error Boundaries

When adding an error.tsx to a route:

Copy'use client';

import * as Sentry from '@sentry/nextjs';
import { useEffect } from 'react';

export default function Error({
  error,
  reset,
}: {
  error: Error & { digest?: string };
  reset: () => void;
}) {
  useEffect(() => {
    // Report to Sentry (if not already captured)
    Sentry.captureException(error);
  }, [error]);

  return (
    <div className="flex flex-col items-center justify-center min-h-[400px] gap-4">
      <h2 className="text-xl font-semibold">Something went wrong</h2>
      <p className="text-muted-foreground">{error.message}</p>
      <button
        onClick={reset}
        className="px-4 py-2 bg-primary text-primary-foreground rounded"
      >
        Try again
      </button>
    </div>
  );
}

Server Action Error Handling

Server actions should NOT throw errors directly. Use the Result pattern:

Copy// ✅ CORRECT - Returns error in result
export const myAction = withAuth(async (params, data) => {
  try {
    const result = await service.doSomething(data);
    if (!result.success) {
      return { success: false, error: result.error.message };
    }
    return { success: true, data: result.data };
  } catch (error) {
    // Sentry captures via instrumentation
    Sentry.captureException(error);
    return { success: false, error: 'An unexpected error occurred' };
  }
});

// ❌ WRONG - Throws error (causes client-side "Load failed")
export const badAction = withAuth(async (params, data) => {
  const result = await service.doSomething(data);
  if (!result.success) {
    throw new Error(result.error.message); // Don't do this!
  }
  return result.data;
});

Client-Side vs Server-Side Errors

Intermittent Errors

Some errors are environmental and not code bugs:

Best Practices

1. Don't over-report: Error boundaries auto-report to Sentry. Avoid double-reporting.
2. Use Result pattern: Server actions return { success, data/error }, not throw.
3. Add boundaries for critical routes: User-facing pages that handle payments, data entry.
4. Log context: Include relevant IDs in error metadata for debugging.
5. Test RLS errors: Some "errors" are RLS working correctly.

Quick Reference

Copy# Check if route has error boundary
ls apps/web/app/path/to/route/error.tsx

# Find all error boundaries
find apps/web/app -name "error.tsx" | head -20

# View Sentry config
cat apps/web/sentry.client.config.ts

Flutter Mobile App Error Handling

The mobile app uses a comprehensive Sentry architecture with multiple layers of error capture.

Architecture Overview

Copyapps/mobile/lib/core/sentry/
├── sentry_service.dart              # Main service with initialization
├── sentry_config.dart               # Configuration constants
├── user_context_manager.dart        # User identification
├── filters/
│   └── pii_filter.dart              # PII sanitization
├── interceptors/
│   └── sentry_dio_interceptor.dart  # HTTP request/response tracking
├── observers/
│   ├── sentry_navigator_observer.dart # Navigation breadcrumbs
│   └── sentry_riverpod_observer.dart  # Provider error tracking
└── widgets/
    └── sentry_error_boundary.dart   # Error boundary with feedback

Why This Architecture?

By default, SentryFlutter.init only captures uncaught exceptions. In Flutter with Riverpod, many errors are caught by the framework:

1. Riverpod AsyncNotifier: Errors go into AsyncValue.error state but don't propagate as uncaught exceptions
2. Try-catch blocks: Errors caught and not rethrown are never seen by Sentry
3. PostgrestException: Supabase database errors are caught by Riverpod providers
4. HTTP errors: Dio catches responses and doesn't throw by default

Core Components

1. SentryService (Initialization)

Location: apps/mobile/lib/core/sentry/sentry_service.dart

Production-grade initialization with:

• 100% error sample rate (capture all errors)
• 20% traces sample rate (performance monitoring)
• PII filtering via beforeSend hook
• Native crash handling enabled
• ANR (Application Not Responding) detection
• User interaction breadcrumbs

Copy// In main.dart
await SentryService.initialize(
  dsn: env.sentryDsn,
  environment: env.name,
  appRunner: () => run(sharedPrefs, useSentryObserver: true),
);

2. SentryRiverpodObserver (Provider Errors)

Location: apps/mobile/lib/core/sentry/observers/sentry_riverpod_observer.dart

Captures errors from Riverpod providers:

• PostgrestException from Supabase queries
• AuthException from authentication failures
• StorageException from file upload errors
• Tags errors with provider name for debugging
• Filters cancelled/aborted operations

CopyProviderScope(
  observers: useSentryObserver ? [SentryRiverpodObserver()] : [],
  child: MyApp(...),
)

3. SentryDioInterceptor (HTTP Errors)

Location: apps/mobile/lib/core/sentry/interceptors/sentry_dio_interceptor.dart

Tracks HTTP requests and captures failures:

• Request/response breadcrumbs for debugging
• Captures 5xx errors and unexpected 4xx (excludes 401/404)
• Sanitizes URLs (removes sensitive query params)
• Included in HttpClient automatically

4. BalleeSentryNavigatorObserver (Navigation)

Location: apps/mobile/lib/core/sentry/observers/sentry_navigator_observer.dart

Tracks navigation for error context:

• Breadcrumbs for route changes
• Sets current_screen tag on errors
• Optional performance transactions

Copy// In router.dart
observers: [
  if (SentryService.isInitialized) BalleeSentryNavigatorObserver(),
],

5. SentryUserContextManager (User Identity)

Location: apps/mobile/lib/core/sentry/user_context_manager.dart

Associates errors with users:

• Sets user ID and masked email on login
• Clears user on logout
• Tracks subscription status

Copy// In user_state_notifier.dart
await SentryUserContextManager.setUser(user);  // On login
await SentryUserContextManager.clearUser();    // On logout

6. PiiFilter (Privacy Protection)

Location: apps/mobile/lib/core/sentry/filters/pii_filter.dart

Sanitizes sensitive data before sending to Sentry:

• Redacts passwords, tokens, API keys
• Masks email addresses and phone numbers
• Applied to events and breadcrumbs

7. SentryErrorBoundary (Widget Error UI)

Location: apps/mobile/lib/core/sentry/widgets/sentry_error_boundary.dart

Error boundary widget with user feedback:

• Catches Flutter errors in widget subtree
• Shows user-friendly error UI
• Allows users to submit feedback via SentryUserFeedback

CopySentryErrorBoundary(
  child: SomeWidget(),
)

Configuration Constants

Supabase Exception Types

Error Capture Matrix

Manual Error Reporting

For errors in try-catch blocks that shouldn't be rethrown:

Copyimport 'package:ballee/core/sentry/sentry_service.dart';

try {
  await someOperation();
} catch (e, stackTrace) {
  // Report to Sentry but handle gracefully
  await SentryService.captureException(e, stackTrace: stackTrace);
  // Show user-friendly error
  showSnackBar('Operation failed');
}
