Refactor handlers for better readability

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

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

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

Start by locating the handlers and utils involved in error handling, then review the current error messages and how failures are reported. Done means the handlers are more readable and errors provide the detailed context needed for debugging and maintenance.
