REST API no results for getUserById() method

Hi Below code always go to error handler.

Could any one help with alternative for JSOM code.

// Variables that we will use in callbacks
var context;
var listItem;

$(document).ready(function () {
    emptyContact("Loading Owner Details...");
    getContactFromList();
});

// Get the value from the Contact column in the Pages list
function getContactFromList() {
    context = SP.ClientContext.get_current();
    listItem = context.get_web().get_lists().getByTitle('Pages').getItemById(_spPageContextInfo.pageItemId);
    context.load(listItem, 'PublishingContact');
    context.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceededc, Function.createDelegate(this, this.onQueryFailedc)));
}

// Delegate method to handle successful async call to load Contact column info.
function onQuerySucceededc(contactColumn) {
    var contact = listItem.get_item('PublishingContact');
    if (contact) {
        getAccountName(contact);
    }
    else {
        emptyContact("Could not retrieve Contact for this page.");
    }
}
// Delegate method to handle failure of async call to load Contact column info.
function onQueryFailedc(sender, args) {
    emptyContact("Could not retrieve Contact for this page.");
}

// Load User Profile information based on the account name of the supplied page Contact
function getAccountName(contact) {
var username = contact.get_lookupValue();
    jQuery.ajax({
        url: _spPageContextInfo.webAbsoluteUrl + "/_api/Web/GetUserById(" + contact.$2Z_1 + ")",
        type: "GET",
        headers: {
            Accept: "application/json; odata=verbose"
        },
        success: displayProfileInformation,
        error: handleAccountNameError
    });
}

function handleAccountNameError(request, textStatus, error) {
    emptyContact("Could not request User Profile for Contact.");
}

// Read and display the detailed User Profile information for supplied Account
function displayProfileInformation(ajaxResponse) {

    var accountName = ajaxResponse.d.LoginName;

    // prepare peoplemanager and profile properties request
    var peopleMgr = new SP.UserProfiles.PeopleManager(context);
    context.load(peopleMgr);
    var profileProperties = peopleMgr.getPropertiesFor(accountName);
    context.load(profileProperties);

    // execute the command against SharePoint
    context.executeQueryAsync(
        // success callback
        function () {

            // contact picture
            $('.q_OwnerImage').children().remove();
            var myPicture = profileProperties.get_pictureUrl();
            if (myPicture == null) {
                myPicture = "";
            }
            var myPictureHTML = '<img src="/_layouts/15/userphoto.aspx?url=' + myPicture + '" alt="Contact"/>';
            var personProperties = profileProperties.get_userProfileProperties();
            $('.q_OwnerImage').append(myPictureHTML);

            alert(personProperties.FirstName);

        },
        // Error handler callback
        handleProfileLoadError);
}

function handleProfileLoadError(request, textStatus, error) {
    emptyContact("Could not load detailed Profile for Contact.");
}

It does not return result when function getAccountName(contact) called. The Ajax didn't respond.

I tried in URL like this

https://mysite/_api/Web/GetUserById(5)

and got below error

<?xml version="1.0" encoding="UTF-8"?>
-<m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><m:code>-2146232832, Microsoft.SharePoint.SPException</m:code><m:message xml:lang="en-US">User cannot be found.</m:message></m:error>
