Modify an Error on Model File

This extension changes a backend error that appears when a user attempts to delete an address that is already in use. The error message in this scenario reads “Unexpected Failure,” the error returned is
errorCode : "ERR_WS_REMOVE_CUSTOMER_ADDRESS" errorMessage : "Unexpected failure" errorStatusCode : "400"
but we need to change it to a different message. will provide a sample code below which is used in SuiteScript

define("Address.Remove", [
	"Address.Model",
	"Application",
	"SC.Models.Init",
	"underscore",
], function (
	AddressModel,
	Application,
	ModelsInit,
	_
) {
	"use strict";

	_.extend(AddressModel, {

		remove: function (id) {
			try {
				return ModelsInit.customer.removeAddress(id);
			}
			catch (e) {
				var promise = Application.processError(e);
				if (promise.errorCode === "ERR_WS_REMOVE_CUSTOMER_ADDRESS") {
					throw 'This address cannot be removed because it is being used.';
				} else {
					return ModelsInit.customer.removeAddress(id)
				}
			}
		}
	});
});
