Improve utils performance

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

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

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

No file, test, or entry point is named. Start by locating the service utilities and their existing error-handling paths, then determine which errors need more descriptive messages; done means the intended service failures provide useful debugging context and the relevant behavior is covered by tests.
