2. Verify SDK initialization by checking if client exists after init
3. Test network connectivity to Sentry ingest endpoint
4. Check sampling configuration to ensure events are not being dropped
5. Temporarily disable beforeSend filtering during debugging
6. Use sentry-cli sourcemaps explain to diagnose source map issues
7. Verify transaction creation and finish calls for performance data
8. Check breadcrumb capture with beforeBreadcrumb debugging
9. Resolve SDK conflicts by ensuring single initialization
10. Run diagnostic script to generate comprehensive health report

Output

• Root cause identified for SDK issues
• Source map problems resolved
• Event capture verified working
• Performance monitoring validated
