Support filtering configuration

**Problem**
When working with core, 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 core error-handling and configuration-filtering entry points. Compare the title's filtering-configuration request with the body’s request for more descriptive errors, then clarify which behavior is in scope. Done should be defined by the expected filtering behavior or error-message improvements, along with tests or examples showing the result.
