Problem

Currently, 4XX HTTP status codes are logged as errors, which can clutter the logs and mislead monitoring systems. Client-side issues should not be considered server errors.

Expected Behavior

• 4XX status codes should be treated as info or excluded from error logs.
• Only 5XX status codes should be logged as errors.

Proposed Solution

• Introduce conditional logging:
  • Log 5XX status codes as errors.
  • Optionally log 4XX as info or ignore them entirely.
