When an API release introduces enum mismatches, number values start arriving as strings, booleans are stringified, or array item shapes change, validate with JSON Schema first, then inspect real paths with key-path extraction, JSON Pointer, JSONPath, and Deep Diff.

Common lookup scenarios
A status field changes from draft/published to processing and breaks enum validation
orderId, total, or paid starts arriving as strings
Array item structures change after an API release
Review number, integer, and boolean drift between backend and frontend contracts
Check schema compatibility before release sign-off
Recommended workflow
- Format the JSON and confirm it parses
- Use Schema validation to find enum, type, and array-path failures
- Use key paths and Pointer to verify the real field location
- Use JSONPath to inspect arrays and nesting
- Use Deep Diff on v1/v2 payloads before updating the schema

When an API release introduces enum mismatches, number values start arriving as strings, booleans are stringified, or array item shapes change, validate with JSON Schema first, then inspect real paths with key-path extraction, JSON Pointer, JSONPath, and Deep Diff.
Does an enum mismatch always mean the backend is wrong?
No. The schema may be outdated, the field may have moved, or the business rule may have changed. Confirm the real payload and contract first.
Why is number or boolean stringification risky?
It can break sorting, calculations, UI logic, database mapping, and downstream schema checks. Type drift is often subtle but release-breaking.
