Pet Clinic AI Chatbot is recommending nutritional products not available in our clinic

Root Cause Analysis

Primary Issue: Data Availability Gap in Nutrition Service

The nutrition service (nutrition-service-nodejs) is experiencing a 50% failure rate with 404 errors when querying for pet nutrition information:
• 6,242 successful requests (200 status)
• 6,088 failed requests (404 status)

This means that when the nutrition agent tries to look up nutritional information for certain pet types, the nutrition service database doesn't
have the data, so it returns a 404 error.

What's Happening in Your System

1. Pet Clinic Agent receives customer questions about pet nutrition
2. Nutrition Agent is invoked to provide nutritional recommendations
3. Nutrition Agent calls the Nutrition Service via GET /nutrition/:pet_type
4. 50% of the time, the nutrition service returns 404 (pet type not found in database)
5. When data is missing, the nutrition agent appears to be hallucinating or making up products instead of gracefully handling the missing data

Hi @awsapm my pet clinic chat bot is recommending nutritional pet products we do not have in our clinic. The above is context we from an initial troubleshooting can you confirm this is the issue?

Exact Numbers:
• 5,011 failed requests (404 errors) to /nutrition/:pet_type
• 6,056 successful requests (200 responses) to /nutrition/:pet_type
• 45% failure rate (5,011 ÷ 11,067 total requests)

Missing Pet Types:
• rabbit - Most frequent 404 errors
• ferret - High failure rate
• turtle - Missing data
• reptile - Not in database

Root Cause: The nutrition service database lacks comprehensive pet type data. When agents query for missing pet types, they receive 404s and likely generate hallucinated product recommendations instead of gracefully handling the data gap.

Immediate Actions:
• Populate nutrition database with missing pet types (rabbit, ferret, turtle, reptile)
• Implement proper 404 error handling in nutrition agent to avoid hallucination
• Add fallback responses when data is unavailable
