Support filtering configuration

**Problem**
When working with helpers, 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 helper implementations and the configuration and error-handling paths in the repository; no specific files or tests are named. Trace how configuration is currently interpreted and how helper failures are reported. Done means filtering configuration is supported and error messages provide the requested debugging detail, with relevant behavior verified through the available checks.
