Support encryption configuration

**Problem**
When working with routes, 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 payload names no files, tests, or entry points, and the title does not match the body. Start by locating route handling and its error paths, then clarify the intended encryption configuration and error-message scope; done means the agreed configuration is supported and the resulting failures provide the requested detail.
