Refactor helpers 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.

The issue does not identify a helper file, entry point, or test to inspect. First locate the helper implementations and their current error-handling paths, then review existing tests or add focused coverage for the affected messages. Done means the relevant errors provide more descriptive debugging information without changing unrelated behavior.
