Handle edge cases in pagination

**Problem**
When working with models, 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 names no files, tests, or entry points. Start by searching for pagination handling and model error construction, then clarify which edge cases and message details are required. Done should include agreed behavior for those cases and tests demonstrating the resulting errors.
