Improve error messages in components

**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 and component error-handling entry points in the repository, then review how current errors are produced. Clarify which messages need more detail and define completion around descriptive errors that improve debugging, with appropriate verification for the affected behavior.
