Improve controllers performance

**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 title mentions controller performance, while the body asks for route error messages and names no files, tests, or entry points. Start by locating the controller and route error-handling entry points, then clarify which messages need changing and what cases must be covered before implementation.
