Refactor services for better readability

**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 lib and identifying the services involved in error handling. Trace the current error messages and determine the intended scope before changing anything; done means errors are handled consistently and provide more descriptive debugging information.
