Refactor utils for better readability

**Problem**
When working with helpers, 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 helper utilities and their existing error-handling paths, then define the required message improvements and verify that errors consistently provide more descriptive debugging context.
