Support logging configuration

**Problem**
When working with lib, 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 inspecting the lib directory and tracing where errors are handled and messages are emitted. Clarify which logging configuration is needed and which error cases should become more descriptive; done means the agreed configuration works and the affected messages provide the debugging context described in the issue.
