When JSON Schema validation reports a missing required field, first confirm whether the field exists in the real API response. Extract leaf key paths, inspect the exact field with JSON Pointer, then review required fields, types, array nesting, and version diffs together.

Common lookup scenarios
Debug missing required fields such as customerEmail or items
Create a field inventory for a long API response
Use JSON Pointer to verify an exact nested array field
Review added, removed, or type-changed fields after an API version update
Prepare API docs or database mapping from response fields
Recommended workflow
- Format JSON and confirm it parses
- Extract key paths to build an API field inventory
- Add business-critical fields to JSON Schema required
- Validate with Schema to find missing fields and type mismatches
- Use Pointer, JSONPath, or Diff to review exact fields and version changes

LookupToolChakanFAQ
When JSON Schema validation reports a missing required field, first confirm whether the field exists in the real API response. Extract leaf key paths, inspect the exact field with JSON Pointer, then review required fields, types, array nesting, and version diffs together.
Does a missing required field always mean the API is wrong?
No. The schema may be outdated, the field may live under data/result, array nesting may be missing, or a newer API version may have renamed the field. Check the real paths first.
Why create a field inventory before writing a schema?
A field inventory turns a long response into reviewable paths, making it easier to decide required fields, document mappings, and compare API versions.
