* Error handling functions for the REST server applications.
|
|
* Notes: This module provides reusable functions to create and handle API errors.
|
|
* It includes functions to create application-specific error objects, throw errors, and handle response errors.
|
|
*
|
|
* However, the error handling logic is just the simplest form of error management.
