Handle edge cases in analytics

**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.

No files, tests, or entry points are named. Start by locating the service and analytics error-handling paths, then identify the edge cases and current messages; done means the requested cases produce descriptive errors and the relevant behavior is covered by the project's existing checks.
