Bug Fixes

Search Entity Type Case Normalization

Search requests using camelCase entity types would fail with GraphQL validation errors:

Invalid input for enum 'EntityType'. No value found for name 'glossaryTerm'

Entity types are now automatically normalized to SCREAMING_SNAKE_CASE format:

Input	Normalized
glossaryTerm	GLOSSARY_TERM
dataProduct	DATA_PRODUCT
corpUser	CORP_USER
dataFlow	DATA_FLOW

This fix is backward-compatible with existing code using uppercase entity types.

Upgrade Instructions

1. Update your go.mod or pull the latest container image
2. No configuration changes required

Verification

# Test search with camelCase entity types
datahub_search query="test" entity_types=["glossaryTerm"]
