Optimize parsers for large datasets

**Problem**
When working with components, 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 parsers and component error-handling paths, then determine how large datasets are processed and where errors are reported. Done means the relevant failures produce more descriptive messages and the parser behavior for large datasets is addressed, with tests covering the changed cases.
