Handle edge cases in caching

**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.

No files, tests, or entry points are named. Start by locating the hook and caching error-handling paths, then inspect existing tests or reproduce the edge cases; done means descriptive errors are emitted for the affected cases and the relevant tests pass.
