Support caching 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 code and its current error-handling paths; the issue does not name files, tests, or an entry point. Clarify whether the goal is caching configuration, more descriptive helper errors, or both, then define the expected messages and a test that demonstrates the completed behavior.
