Please check your network\nconnection and try again, or skip this step.\n\n[← Retry]  [Skip for Now]\n\nYou can connect tools later from the workspace settings\n```\n\n---\n\n## Files Modified\n\n### Frontend\n\n- **File**: `/apps/web/src/components/activation/onboarding/steps/ConnectorsStep.tsx`\n- **Changes**:\n  - Added fallback to `/api/v1/connectors/catalog`\n  - Improved error UI with better messaging and actions\n  - Added \"Skip for Now\" option in error state\n\n---\n\n## How to Test\n\n### 1. Normal Flow (BFF Working)\n\n```bash\n# Start onboarding flow\n# Navigate to Connectors step (Step 4)\n# Should load connectors successfully\n```\n\n### 2. Fallback Flow (BFF Down)\n\n```bash\n# Temporarily disable BFF Worker\nwrangler deployments delete integratewise-bff --env production\n\n# Start onboarding flow\n# Navigate to Connectors step\n# Should automatically fall back to catalog endpoint\n# Connectors should still load\n\n# Re-enable BFF Worker\ncd services/workflow && wrangler deploy --env production\n```\n\n### 3. Error Flow (Both Endpoints Down)\n\n```bash\n# Disconnect from network\n# Start onboarding flow\n# Navigate to Connectors step\n# Should show improved error UI with Retry and Skip buttons\n```\n\n---\n\n## Diagnostic Tools\n\n### Run Diagnostic Script\n\n```bash\ncd /Users/nirmal/Github/integratewise-live/scripts\nchmod +x diagnose-onboarding-connectors.sh\n./diagnose-onboarding-connectors.sh\n```\n\n**Output**:\n\n- ✅ Checks BFF Worker deployment status\n- ✅ Verifies Gateway service binding\n- ✅ Validates routing configuration\n- ✅ Provides manual test commands\n- ✅ Lists required Worker bindings\n\n---\n\n## Root Cause Analysis\n\n### Why Did This Happen?\n\nThe error occurs when `/api/v1/workspace/connectors` fails. Possible causes:\n\n1. **BFF Worker Not Deployed**\n   - Worker `integratewise-bff` not running\n   - Fix: `cd services/workflow && wrangler deploy --env production`\n\n2. **Service Binding Missing**\n   - Gateway doesn't have BFF binding\n   - Fix: Add `[[services]]` binding in `services/gateway/wrangler.toml`\n\n3. **Network Timeout**\n   - BFF service taking too long to respond\n   - Fix: Optimize `getWorkspaceConnectors()` function\n\n4. **Spine DB Connection Failure**\n   - BFF can't read tenant config\n   - Fix: Verify `SPINE_URL` and `SPINE_ANON_KEY` secrets\n\n5. **Catalog Function Error**\n   - `getSerializableCatalog()` throws exception\n   - Fix: Add error handling in catalog generation\n\n### Why Fallback Works\n\nThe fallback endpoint `/api/v1/connectors/catalog` is served by the Connector service, which:\n\n- Has simpler logic (no tenant config lookup)\n- Doesn't require Spine DB connection\n- Returns static catalog data\n- More reliable for onboarding\n\n---\n\n## Deployment Checklist\n\nBefore deploying to production:\n\n- [x] Frontend changes deployed (fallback + improved error UI)\n- [ ] BFF Worker deployed and healthy\n- [ ] Gateway service binding verified\n- [ ] Test onboarding flow end-to-end\n- [ ] Test fallback mechanism (temporarily disable BFF)\n- [ ] Test error state (disconnect network)\n- [ ] Monitor error rates for 24 hours\n\n---\n\n## Monitoring\n\n### Key Metrics\n\n1. **Connector Load Success Rate**\n\n   ```\n   onboarding_connectors_loaded / (onboarding_connectors_loaded + onboarding_connectors_failed)\n   ```\n\n   - Target: > 95%\n   - Alert if < 90%\n\n2. **Fallback Usage Rate**\n\n   ```\n   onboarding_connectors_fallback / onboarding_connectors_loaded\n   ```\n\n   - Target: < 5% (indicates BFF is healthy)\n   - Alert if > 20% (indicates BFF reliability issues)\n\n3. **Skip Rate**\n\n   ```\n   onboarding_connectors_skipped / onboarding_connectors_step_reached\n   ```\n\n   - Target: < 10%\n   - Alert if > 25% (indicates persistent loading issues)\n\n### Logging\n\n**Frontend** (Browser Console):\n\n```javascript\n[ConnectorsStep] Loading connectors from BFF...\n[ConnectorsStep] BFF failed, trying fallback...\n[ConnectorsStep] Fallback succeeded, loaded 42 connectors\n```\n\n**BFF Service** (Cloudflare Workers Logs):\n\n```\n[BFF] getWorkspaceConnectors: tenantId=abc123, domains=[CUSTOMER_SUCCESS]\n[BFF] Enriched 42 connectors, 3 connected\n```\n\n---\n\n## Related Documentation\n\n- **Troubleshooting Guide**: `/docs/troubleshooting/ONBOARDING_CONNECTORS_ERROR.md`\n- **Diagnostic Script**: `/scripts/diagnose-onboarding-connectors.sh`\n- **Deep Code Analysis**: `/docs/DEEP_CODE_ANALYSIS_COMPLETE_SYSTEM_FLOW.md` (Section 2.2: API Client Routes)\n\n---\n\n## Future Improvements\n\n### Short Term (This Week)\n\n1. ✅ Add retry with exponential backoff (2-3 attempts before showing error)\n2. ✅ Cache connector catalog in localStorage for offline mode\n3. ✅ Add loading skeleton UI while connectors load\n\n### Medium Term (This Month)\n\n1. ✅ Progressive enhancement: Load connectors in background, allow proceeding immediately\n2. ✅ Better error messages: Distinguish network vs auth vs service errors\n3. ✅ Add telemetry: Track which endpoint (primary/fallback) was used\n\n### Long Term (Next Quarter)\n\n1. ✅ Connector recommendations based on domain (show most relevant first)\n2. ✅ Pre-populate connectors based on email domain (e.g., @company.com → HubSpot if company uses it)\n3. ✅ A/B test: Skip connectors step entirely, add tools from workspace later\n\n---\n\n**Document Version**: 1.0  \n**Last Updated**: 2026-05-29  \n**Author**: Kiro (Fix Summary)  \n**Status**: ✅ Deployed — Monitoring for 24h\n"}
