Refactor hooks for better readability

**Problem**
When working with parsers, 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 parser hooks and their current error-handling paths. Read the existing parser-related checks, if present, before deciding the scope. Done means the hooks are easier to read and parser failures provide more descriptive error messages.
