Handle edge cases in analytics

**Problem**
When working with auth, 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 auth-related error handling, then determine which failure cases need clearer messages. Done means the agreed auth errors provide more descriptive debugging information, but the required cases and wording are not specified.
