Pet clinic agents are recommending invalid nutritional products

[liustve]

Root Cause Analysis

The Problem: Your nutrition service database has limited product coverage, but your chatbot is trying to recommend products for exotic pets that aren't in your inventory.

Key Findings:

1. Limited Product Database: Your nutrition service only has products for these pet types:
   • ✅ Available: cat, dog, bird, hamster, snake (limited)
   • ❌ Missing: rabbit, exotic pets, chameleon, chinchilla, bearded dragon, serval, peacock, tortoise, hedgehog, sloth, porcupine, degu, tarantula, ferret, turtle, emu, llama, frog, raccoon, armadillo, amphibian, coatimundi

2. High Error Rate: 12.41% error rate on nutrition lookups, with 8,474+ failed requests for unsupported pet types

3. Most Problematic Requests:
   • Rabbit nutrition: 1,103 failed requests (highest volume)
   • Exotic pets: 88+ failed requests
   • Chameleon: 131 failed requests
   • Chinchilla: 33 failed requests

4. System Architecture Issue: Your pet clinic agent calls the nutrition agent, which then queries the nutrition service. When the service returns 404 (product not found), the agents may still generate recommendations based on their
   training data rather than your actual inventory.

Recommended Solutions

Immediate Fixes:

1. Update Nutrition Database: Add products for the most requested missing pet types (rabbit, exotic pets, chameleon, etc.) or add explicit "not available" entries

2. Improve Error Handling: Modify your nutrition agent to:
   • Return clear "product not available" messages instead of generating recommendations
   • Suggest alternative products you do carry
   • Redirect to general pet care advice when specific nutrition products aren't available

3. Agent Prompt Engineering: Update your pet clinic agent's system prompt to:
   • Only recommend products that exist in your database
   • Check product availability before making recommendations
   • Provide fallback responses for unsupported pet types

🎯 Application observability for AWS Investigation Complete

Investigation completed successfully! Here are the results:

Root Cause: The nutrition service database only contains 6 pet types (cat, dog, lizard, snake, bird, hamster) but receives requests for 20+ different pet types, causing 8,483 404 errors (12.41% error rate).

Key Findings:
• Database Gap: Missing products for rabbit, exotic pets, chameleon, chinchilla, bearded dragon, etc.
• Error Pattern: All 8,483 errors are 404 responses from GET /nutrition/:pet_type
• Service Impact: High error rate affecting AI agent recommendations

Immediate Solutions:

1. Expand Database Coverage - Add missing pet types to db-seed.js:
   javascript
   { pet_type: 'rabbit', facts: 'High-fiber pellets, hay, and fresh vegetables', products: 'BunnyBest Timothy Pellets, HopHappy Hay Mix, CarrotCrunch Vitamin C' },
   { pet_type: 'chameleon', facts: 'Live insects and calcium/vitamin D3 supplements', products: 'ChameleonChoice Cricket Supply, ColorChange Calcium Plus, ReptileRainbow UVB Support' }

2. Improve Error Handling - Modify nutrition service to return structured responses for unsupported pets instead of generic 404s

3. Agent Logic Update - Configure AI agents to handle 404 responses gracefully and suggest available alternatives

The issue stems from a mismatch between the limited nutrition database (6 pet types) and the broader range of pets the AI agents attempt to provide recommendations for (20+ types).
