When JSONPath returns no matches, validate the JSON first, inspect real key paths, then check the root $, array [*] steps, field casing, and response nesting. If the path is uncertain, use $..field briefly, then narrow it to an exact expression.

Common lookup scenarios
JSONPath returns no match even though the field exists
Extract sku, id, or code from nested orders[*].items[*] arrays
Debug data/result root wrappers and casing mismatches
Combine JSONPath, JSON Pointer, and key paths for field mapping review
Recommended workflow
- Format JSON to confirm it parses
- Extract key paths to inspect the real structure
- Change $.items.sku to $.items[*].sku for arrays
- Use $..field temporarily when nesting is unclear
- Verify final mappings with JSON Pointer or Schema

LookupToolChakanFAQ
When JSONPath returns no matches, validate the JSON first, inspect real key paths, then check the root $, array [*] steps, field casing, and response nesting. If the path is uncertain, use $..field briefly, then narrow it to an exact expression.
Why does JSONPath return empty when the field exists?
Common causes are the wrong root, missing [*] for arrays, casing differences, or an extra data/result/items wrapper in the real response.
When should I use $..field?
Use $..field for temporary discovery across unknown nesting. For production docs or repeatable checks, narrow it to a precise path so duplicate field names do not get mixed in.
