🛠️ Troubleshooting

Common Issues & Solutions

❌ Issue: Messages not reaching n8n
✅ Solution:
   1. Check NEXT_PUBLIC_N8N_WEBHOOK_URL environment variable
   2. Verify webhook endpoint is active in n8n
   3. Check network connectivity and CORS settings
   4. Review n8n workflow execution logs

❌ Issue: Voice messages not processing
✅ Solution:
   1. Verify Web Speech API browser support
   2. Check microphone permissions
   3. Validate voice processing workflow in n8n
   4. Test with smaller audio files first

❌ Issue: Streaming responses laggy
✅ Solution:
   1. Check WebSocket connection stability
   2. Optimize message chunking in n8n workflow
   3. Reduce streaming frequency if needed
   4. Monitor network latency between services

❌ Issue: UI not updating on message send
✅ Solution:
   1. Verify React state updates in useChatWithN8n hook
   2. Check for JavaScript errors in browser console
   3. Validate message object structure
   4. Test with simple text messages first
