Optimize components for large datasets

**Problem**
When working with core, 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 only the core and provides no file, test, or entry-point path. Start by locating the core error-handling paths, then identify the affected cases and verify that their messages are more descriptive, as requested.
