Walkthrough

Added error logging to JWT authentication filter's exception handler using a static log import. The modification logs exception messages and stack traces when JWT processing fails, prior to returning the existing 401 unauthorized response with JSON error body.

Poem

🐰 A log statement hops into view,
Capturing JWT errors fresh and true,
No flow changes, just visibility gained,
Stack traces now beautifully retained! 📝
