Update lib documentation

**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.

Start by locating the lib documentation and the component error-handling entry points; the issue names no files or tests. Clarify which component errors and messages are in scope, then verify that the resulting documentation or behavior provides more descriptive debugging information.
