Improve error messages in services

**Description**
Currently helpers lacks proper filtering support.

**Proposed solution**
Add configurable filtering with sensible defaults.

**Priority**: Low/Medium

Start by locating the services and helpers referenced in the issue and inspect how errors and filtering currently work. Clarify whether the intended scope is improved error messages, configurable filtering, or both; done means the agreed filtering behavior and sensible defaults are implemented and the resulting errors are clear.
