Add configuration options for notifications

**Problem**
When working with services, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue names no files, tests, or entry points. Start by locating the service error-handling and notification configuration areas, then clarify the intended options and message cases with a maintainer; done means the requested configuration and more descriptive errors are covered by appropriate checks.
