Frontend Troubleshooting Guide

Issue: No Content Appearing

Possible Causes

Next.js Compilation Issue
- Next.js may still be compiling
- Check for compilation errors in the terminal
- Wait for "Ready" message in dev server
Missing Dependencies
- React Query, Wagmi, or other dependencies may not be loaded
- Check browser console for errors
Provider Issues
- Providers (QueryClient, Wagmi, Session) may be failing silently
- Check browser console for React errors
CSS Not Loading
- Tailwind CSS may not be compiled
- Check if globals.css is imported correctly

Solutions

1. Check Dev Server Status

# Check if Next.js is running
Get-NetTCPConnection -LocalPort 3000 -State Listen

# Check process
Get-Process node | Where-Object { $_.Id -eq (Get-NetTCPConnection -LocalPort 3000).OwningProcess }

2. Restart Dev Server

cd webapp
# Stop current server (Ctrl+C)
npm run dev

3. Clear Next.js Cache

cd webapp
Remove-Item -Recurse -Force .next -ErrorAction SilentlyContinue
npm run dev

4. Check Browser Console

Open browser DevTools (F12)
Check Console tab for errors
Check Network tab for failed requests

5. Verify Environment Variables

# Check if .env.local exists
Test-Path webapp/.env.local

# Create minimal .env.local if missing
@"
NEXT_PUBLIC_ORCH_URL=http://localhost:8080
NEXTAUTH_SECRET=dev-secret-change-in-production
"@ | Out-File -FilePath webapp/.env.local

6. Check for TypeScript Errors

cd webapp
npm run build

Quick Fixes

Fix 1: Ensure Providers Load

The providers.tsx file should wrap the app. Check that it's imported in layout.tsx.

Fix 2: Add Error Boundary

The ErrorBoundary component should catch and display errors. Check browser console.

Fix 3: Verify API Endpoints

Check that the orchestrator is running and accessible:

Invoke-WebRequest -Uri "http://localhost:8080/health" -UseBasicParsing

Common Issues

Issue: Blank Page

Cause: React hydration error or provider failure Fix: Check browser console, verify all providers are configured

Issue: Timeout

Cause: Next.js still compiling or stuck Fix: Restart dev server, clear .next cache

Issue: Styling Missing

Cause: Tailwind CSS not compiled Fix: Check globals.css import, verify Tailwind config
