Support logging configuration

**Problem**
When working with routes, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue names no files, tests, or entry points. Start by locating route handling and the existing logging or error-message configuration, then determine the intended configuration surface and document the detailed errors that should appear; done means the behavior is specified and covered by relevant checks.
