A path segment, key name, or filter condition may not match the current JSON structure.

JSONPath Testing Guidance
JSONPath queries are fastest to debug when you test against realistic payload samples and iterate from simple selectors to filters.
- Start with broad selectors, then narrow with predicates.
- Validate array indexes and wildcard behavior against edge cases.
- Keep sample data close to production shape for reliable results.

JSONPath Tester FAQ
Are JSONPath implementations always identical?
No. Feature support can differ across libraries and platforms.
Should I validate JSON before testing paths?
Yes. Invalid JSON prevents correct path evaluation and can hide real query issues.
