Improve middleware performance

**Problem**
When working with utils, 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 utils paths related to error handling, then inspect how their current messages are produced. Done means the relevant errors provide more descriptive debugging information and the existing behavior remains covered by the project's checks.
