Improve error messages in config

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

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

**Priority**: Low/Medium

Start by locating the configuration handling and the code that processes types and filtering; the payload does not name specific files or tests. Clarify whether the goal is improved error messages, configurable filtering, or both, then verify that sensible defaults and the expected error behavior are covered.
