Add TypeScript types for services

**Problem**
When working with hooks, 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 reconciling the title's request for TypeScript service types with the body’s request for more descriptive hook errors; no file or test is identified. Locate the service and hook entry points, then confirm the intended scope with the maintainers. Done should include the agreed type or error-handling changes and tests or examples covering the resulting behavior.
