Critical Bugs Found

BUG-003: Refresh Token Endpoint Returns 500 Error

Severity: CRITICAL Priority: P0 - Fix Immediately Status: Open Affected Endpoint: POST /api/auth/refresh

Description: The /api/auth/refresh endpoint consistently returns 500 Internal Server Error when attempting to refresh a valid refresh token.

Steps to Reproduce:

1. Register a new tenant via POST /api/tenants/register
2. Extract refreshToken from response
3. Call POST /api/auth/refresh with body: {"refreshToken": "<token>"}
4. Observe 500 error

Expected Result: 200 OK with new accessToken and refreshToken

Actual Result:

{
  "type": "https://tools.ietf.org/html/rfc7231#section-6.6.1",
  "title": "Internal Server Error",
  "status": 500,
  "detail": "An unexpected error occurred.",
  "instance": "/api/auth/refresh",
  "traceId": "00-43347aab2f3a768a0cc09eec975b378a-b81b31c537809552-00"
}

Impact:

• Users cannot refresh their access tokens
• Users will be forced to re-login every 15 minutes
• Token rotation security feature is completely broken
• Blocks all Day 5 Phase 1 functionality

Root Cause Analysis: Likely causes (in order of probability):

1. Missing database table: refresh_tokens table may not exist
2. Missing migration: Database schema not up to date
3. Database connection issue: Connection string or permissions
4. EF Core configuration: Entity mapping issue

Recommended Fix:

1. Run database migrations: dotnet ef database update
2. Verify refresh_tokens table exists in database
3. Check application logs for detailed exception stack trace
4. Verify RefreshTokenRepository can save/query tokens

---

BUG-004: Login Endpoint Returns 500 Error

Severity: CRITICAL Priority: P0 - Fix Immediately Status: Open Affected Endpoint: POST /api/auth/login

Description: The /api/auth/login endpoint returns 500 Internal Server Error when attempting to login with valid credentials.

Steps to Reproduce:

1. Register a new tenant
2. Attempt to login with the same credentials
3. Call POST /api/auth/login with:

   {
     "tenantSlug": "test-1234",
     "email": "admin@test.com",
     "password": "Admin@1234"
   }
   

4. Observe 500 error

Expected Result: 200 OK with accessToken, refreshToken, user, and tenant data

Actual Result:

{
  "status": 500,
  "title": "Internal Server Error",
  "instance": "/api/auth/login",
  "traceId": "00-e608d77cce3ed7e30eb99296f4746755-12a1329633f83ec7-00"
}

Impact:

• Users cannot login after registration
• Blocks all returning users
• Password persistence testing impossible
• Role persistence testing impossible
• Blocks Day 5 Phase 2 and Phase 3 tests

Root Cause Analysis: Same as BUG-003 - likely the GenerateRefreshTokenAsync call in LoginCommandHandler is failing due to missing refresh_tokens table.

Location: LoginCommandHandler.cs line 74-78:

// 6. Generate refresh token
var refreshToken = await _refreshTokenService.GenerateRefreshTokenAsync(
    user,
    ipAddress: null,
    userAgent: null,
    cancellationToken);

Recommended Fix: Same as BUG-003 - ensure database migrations are applied.

Deployment Recommendation

🔴 DO NOT DEPLOY

Rationale:

1. 2 Critical (P0) bugs blocking core functionality
2. 57% pass rate - far below 95% threshold
3. Login completely broken - no user can login after registration
4. Token refresh broken - users forced to re-login every 15 minutes
5. 38% of acceptance criteria failed
6. All E2E critical user flows broken

Blocking Issues Summary

Must Fix Before Deployment:

1. ❌ BUG-003: Fix /api/auth/refresh endpoint
2. ❌ BUG-004: Fix /api/auth/login endpoint
3. ❌ Run database migrations
4. ❌ Verify refresh_tokens table exists
5. ❌ Re-run full test suite to verify fixes

Estimated Fix Time

• Database migration: 5 minutes
• Verification testing: 10 minutes
• Total: ~15 minutes

Next Steps:

1. Backend engineer: Run dotnet ef database update
2. Backend engineer: Verify database schema
3. QA: Re-run full test suite
4. QA: Verify all 14 tests pass
5. QA: Update deployment recommendation

Recommendations

Immediate Actions (Before Next Test Run)

1. Database Migrations

   cd colaflow-api
   dotnet ef database update --project src/ColaFlow.API
   

2. Verify Database Schema

   -- Check if refresh_tokens table exists
   SELECT table_name
   FROM information_schema.tables
   WHERE table_schema = 'identity'
   AND table_name = 'refresh_tokens';
   
   -- Verify columns
   SELECT column_name, data_type
   FROM information_schema.columns
   WHERE table_schema = 'identity'
   AND table_name = 'refresh_tokens';
   

3. Check Application Logs

   • Review console output for stack traces
   • Look for EF Core exceptions
   • Verify database connection string

Code Review Findings

Positive:

• ✅ Service implementations are well-structured
• ✅ Dependency injection properly configured
• ✅ Error handling in controllers
• ✅ Security best practices (token hashing, secure random generation)
• ✅ RBAC implementation follows design

Concerns:

• ⚠️ No database migration scripts found
• ⚠️ No explicit database initialization in startup
• ⚠️ Exception details hidden in production (good for security, bad for debugging)

Testing Recommendations

1. Add Health Check Endpoint

   [HttpGet("health/database")]
   public async Task<IActionResult> HealthCheck()
   {
       var canConnect = await _dbContext.Database.CanConnectAsync();
       return Ok(new { database = canConnect });
   }
   

2. Add Integration Tests

   • Unit tests for RefreshTokenService
   • Integration tests for database operations
   • E2E tests for critical user flows

3. Improve Error Logging

   • Log full exception details to console in Development
   • Include stack traces in trace logs

---

Conclusion

The Day 5 implementation shows good progress on RBAC and basic authentication, but critical failures in the refresh token and login endpoints block deployment.

The root cause appears to be missing database migrations rather than code defects. The code quality is good, and the architecture is sound.

Once the database schema is updated and migrations are applied, a full re-test is required before deployment can be approved.
