Add configuration options for export

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

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

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

No files, tests, or entry points are named. Start by locating the store error-handling paths and the export configuration entry point, then clarify whether the goal is detailed store errors, export options, or both; done should be defined by explicit affected cases and tests for the agreed behavior.
