Improve middleware performance

**Problem**
When working with components, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue names no files, tests, or concrete middleware entry point, and its title conflicts with the body’s focus on error messages. Start by locating the middleware and component error-handling entry points, then clarify whether completion means measurable performance improvement, more descriptive errors, or both, with tests covering the agreed behavior.
