Installation Issues

npm install fails with permission errors

Symptoms:

• EACCES permission denied errors
• EPERM operation not permitted

Solutions:

1. Don't use sudo with npm. Instead, fix npm permissions:

   bashCopy

   mkdir ~/.npm-global
   npm config set prefix '~/.npm-global'
   echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
   source ~/.bashrc
   

2. Use a Node version manager like nvm or fnm:

   bashCopy

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
   nvm install 20
   nvm use 20
   

Build fails with "out of memory"

Symptoms:

• JavaScript heap out of memory
• Build process killed

Solutions:

1. Increase Node.js memory limit:

   bashCopy

   export NODE_OPTIONS="--max-old-space-size=4096"
   npm run build
   

2. Use the standalone build (recommended for production):

   bashCopy

   npm run build
   # This creates .next/standalone with optimized bundle
   

Optional dependencies fail to install

Symptoms:

• Warnings about twilio, resend, or @aws-sdk/client-sns
• These are optional and won't prevent OpsKnight from running

Solution: Install only the providers you need:

# For Twilio SMS/WhatsApp
npm install twilio

# For Resend email
npm install resend

# For AWS SNS
npm install @aws-sdk/client-sns

# For SendGrid email
npm install @sendgrid/mail

Database Connection Problems

"Connection refused" or "Connection timed out"

Symptoms:

• ECONNREFUSED error
• Connection timed out after deployment

Solutions:

1. Verify PostgreSQL is running:

   bashCopy

   # Check if PostgreSQL is running
   pg_isready -h localhost -p 5432
   
   # For Docker
   docker ps | grep postgres
   

2. Check your DATABASE_URL format:

   textCopy

   postgresql://USER:PASSWORD@HOST:PORT/DATABASE?sslmode=require
   

3. For cloud databases (Supabase, Neon, etc.):

   • Enable SSL: Add ?sslmode=require to the connection string
   • Check firewall rules allow your IP
   • Verify the database is in the same region as your app

"Prisma Client not initialized"

Symptoms:

• @prisma/client did not initialize yet
• PrismaClient is unable to be run in the browser

Solutions:

1. Regenerate Prisma Client:

   bashCopy

   npx prisma generate
   

2. For production builds:

   bashCopy

   # Include in your build script
   npm run build  # This runs prisma generate automatically
   

Migration errors

Symptoms:

• Migration failed during deployment
• P3009: migrate found failed migrations

Solutions:

1. Check migration status:

   bashCopy

   npx prisma migrate status
   

2. Use the safe migration script:

   bashCopy

   npm run prisma:migrate:safe
   

3. For failed migrations, use auto-recovery:

   bashCopy

   npm run prisma:auto-recover
   

4. Manual recovery (last resort):

   sqlCopy

   -- Connect to your database and mark failed migration as applied
   UPDATE "_prisma_migrations"
   SET finished_at = NOW(), applied_steps_count = 1
   WHERE migration_name = 'YYYYMMDDHHMMSS_migration_name'
   AND finished_at IS NULL;
   

Authentication Failures

"Invalid credentials" but credentials are correct

Symptoms:

• Login fails with valid email/password
• "Invalid credentials" error

Solutions:

1. Check if the user exists:

   bashCopy

   # Use the OpsKnight CLI
   npm run ops user:list
   

2. Reset the password:

   bashCopy

   npm run ops user:reset-password --email [email protected]
   

3. Verify the encryption key hasn't changed (see Encryption Key Issues)

Session expires immediately

Symptoms:

• Logged out after every page refresh
• "Session expired" error immediately after login

Solutions:

1. Check NEXTAUTH_URL matches your actual URL:

   bashCopy

   # .env
   NEXTAUTH_URL=https://your-actual-domain.com
   

2. Verify cookies are being set:

   • Open browser DevTools → Application → Cookies
   • Look for next-auth.session-token cookie
   • Check if Secure flag matches your protocol (HTTPS vs HTTP)

3. For reverse proxy setups, ensure headers are forwarded:

   nginxCopy

   # nginx example
   proxy_set_header Host $host;
   proxy_set_header X-Real-IP $remote_addr;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header X-Forwarded-Proto $scheme;
   

OIDC/SSO login fails

Symptoms:

• "Invalid state" or "Invalid nonce" errors
• Redirect loop during SSO login

Solutions:

1. Verify callback URL is configured correctly:

   • Callback URL should be: https://your-domain.com/api/auth/callback/oidc
   • This must exactly match what's configured in your IdP

2. Check the OIDC configuration in Settings → Security → SSO

3. For Azure AD: Ensure email claim is included in the token

4. Enable debug logging (see Debug Logging)

Notification Delivery Issues

Emails not being sent

Symptoms:

• No emails received
• "Email provider not configured" warnings in logs

Solutions:

1. Verify email provider is configured:

   • Go to Settings → System → Email Providers
   • Ensure a provider is enabled and has valid credentials

2. Check the from email address:

   • For Resend/SendGrid: Domain must be verified
   • For SMTP: Check your mail server allows this sender

3. Test email delivery:

   • Go to Settings → Notifications → Test Email
   • Check logs for delivery errors

SMS not being delivered

Symptoms:

• SMS notifications not received
• "Twilio package not installed" error

Solutions:

1. Install the Twilio package:

   bashCopy

   npm install twilio
   

2. Verify Twilio configuration:

   • Account SID and Auth Token in Settings → System → Notification Providers
   • From Number must be a valid Twilio phone number
   • For trial accounts: Target number must be verified

3. Check phone number format:

   • Must be in E.164 format: +15551234567
   • Include country code

Push notifications not working

Symptoms:

• "Push notifications not enabled" error
• Browser doesn't prompt for notification permission

Solutions:

1. Check VAPID keys are configured:

   • Settings → System → Notification Providers → Web Push
   • Generate new keys if needed:
     bashCopy

     npx web-push generate-vapid-keys
     

2. Verify HTTPS:

   • Push notifications only work over HTTPS
   • Exception: localhost for development

3. Check browser permissions:

   • Click the lock icon in the URL bar
   • Ensure notifications are "Allowed"

Performance Troubleshooting

Slow page loads

Symptoms:

• Pages take several seconds to load
• Timeout errors

Solutions:

1. Check database query performance:

   bashCopy

   # Enable query logging
   LOG_LEVEL=debug npm start
   

2. Optimize database:

   sqlCopy

   -- Check for missing indexes
   SELECT schemaname, tablename, indexname
   FROM pg_indexes
   WHERE schemaname = 'public';
   
   -- Analyze tables
   ANALYZE;
   

3. Increase connection pool:

   textCopy

   DATABASE_URL="...?connection_limit=20"
   

High memory usage

Symptoms:

• Server runs out of memory
• OOM killer terminates process

Solutions:

1. For standalone builds, memory usage should be lower:

   bashCopy

   node .next/standalone/server.js
   

2. Set appropriate memory limits:

   bashCopy

   # Docker
   docker run --memory=512m opsknight
   
   # Node.js
   NODE_OPTIONS="--max-old-space-size=512" node server.js
   

3. Check for memory leaks using Node.js diagnostics:

   bashCopy

   node --inspect .next/standalone/server.js
   # Connect Chrome DevTools to take heap snapshots
   

Cron jobs not running

Symptoms:

• Escalations not triggered on schedule
• Scheduled jobs stuck as "pending"

Solutions:

1. Check cron scheduler status:

   • Go to Settings → System → Background Jobs
   • Verify "Cron Scheduler" shows as "Running"

2. Enable internal cron:

   bashCopy

   # Default is enabled
   ENABLE_INTERNAL_CRON=true
   

3. Check for lock issues:

   sqlCopy

   -- View scheduler state
   SELECT * FROM "CronSchedulerState";
   
   -- Clear stale lock if needed
   UPDATE "CronSchedulerState"
   SET "lockedBy" = NULL, "lockedAt" = NULL
   WHERE id = 'singleton';
   

Debug Logging

Enable verbose logging

# Set log level
LOG_LEVEL=debug npm start

# For JSON output (better for log aggregation)
LOG_FORMAT=json npm start

Log levels

Common log locations

• Application logs: stdout/stderr (or configured log destination)
• Database logs: PostgreSQL log files
• Cron scheduler: Look for [Cron] prefix in logs
• Notifications: Look for component: 'sms', component: 'email', etc.

Encryption Key Issues

If you see CRITICAL: Encryption Key failed canary check:

1. The encryption key has changed or is invalid
2. Data encrypted with the old key cannot be decrypted

Recovery steps:

1. Restore the original ENCRYPTION_KEY from backup
2. If key is lost, you'll need to re-enter all encrypted credentials (API keys, etc.)
