Support encryption configuration

**Problem**
When working with data, 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 data-handling and error-reporting paths in the repository. Confirm which encryption configuration and failure cases are in scope, then define detailed error messages and verify them against the affected workflows.
