Handle edge cases in analytics

**Problem**
When working with handlers, 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 analytics handlers and tracing their current error paths. Review how handler failures are reported, then identify the edge cases that need distinct, more descriptive messages. Done means the relevant failures provide useful debugging context and the existing behavior remains intact.
