Support serialization 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.

The issue names no files, tests, or entry points. Start by locating the serialization configuration and current error-handling path, then clarify the expected configuration and provide examples of the detailed messages; done should include agreed behavior and tests covering it.
