🔧 Troubleshooting Guide

Issue: Assistant doesn't call functions

Check:

OpenAPI spec uploaded correctly
Function names match spec: search_knowledge_base, get_statistics, check_system_health
Server URL is correct and accessible

Solution:

Re-upload OpenAPI spec
Test endpoints manually: curl <endpoint>/health
Check Azure AI Foundry logs

Issue: "Function execution failed"

Possible Causes:

RAG service not running
Network connectivity issues
Invalid Aura credentials

Debug:

# Test endpoint directly
curl -X POST <your-url>/query \
  -H "Content-Type: application/json" \
  -d '{"question": "test", "k": 3}'

# Check health
curl <your-url>/health

# View Container App logs (if using Azure)
az containerapp logs show \
  --name neo4j-rag-agent \
  --resource-group rg-neo4j-rag-bitnet

Issue: Slow responses

Solutions:

Pre-warm cache: Run common queries before demo
Check model loading: First query is slower (loads embeddings)
Monitor Aura: Check database connection health

Performance Targets:

First query: <5s (acceptable with model loading)
Cached queries: <100ms (validated at 13.5ms)
Health/stats: <500ms (validated at ~300ms)
