Refactor components for better readability

**Problem**
When working with middleware, 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 middleware implementation and reading its current error-handling paths. Define which failures need more descriptive messages and verify that the resulting messages provide useful debugging context without changing unrelated middleware behavior.
