Support pagination configuration

**Problem**
When working with config, 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 files, tests, or entry points are identified. Start by locating the configuration handling and existing error paths, then determine the intended pagination settings and error cases; done means pagination configuration is supported and failures produce detailed, useful messages.
