Consider deprecating old hooks API

**Problem**
When working with controllers, 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 controller paths responsible for handling errors and review how their current messages are produced. The issue does not name files or tests, so first identify the relevant entry points and existing coverage. Done means error handling is improved and messages provide more useful debugging detail.
