Paging in MS Graph API

Question

Graph API Paging explains that the response would contain a field @odata.nextLink which would contain a skiptoken pointing to the next page of contents.

When I test the API, I'm getting a fully-qualified MS Graph URL which contains the skiptoken as a query param. E.g. Below is the value I got for the field @odata.nextLink in the response JSON. https://graph.microsoft.com/v1.0/users?$top=25&$skiptoken=X%27445370740200001E3A757365723134406F33363561702E6F6E6D6963726F736F66742E636F6D29557365725F31363064343831382D343162382D343961372D383063642D653136636561303437343437001E3A7573657235407368616C696E692D746573742E31626F74322E696E666F29557365725F62666639356437612D333764632D343266652D386335632D373639616534303233396166B900000000000000000000%27

Is it safe to assume we'll always get the full URL and not just the skiptoken? Because if it's true, it helps avoid parsing the skiptoken and then concatenating it to the existing URL to form the full URL ourselves.

EDIT - Compared to MS Graph API, response obtained from Azure AD Graph API differs in that the JSON field @odata.nextLink contains only the skipToken and not the fully-qualified URL.

if you would like to have all users in single list, you can achieve that using the code that follows:

public static async Task<IEnumerable<User>> GetUsersAsync()
    {
        var graphClient = GetAuthenticatedClient();
        List<User> allUsers = new List<User>();
        var users = await graphClient.Users.Request().Top(998)
           .Select("displayName,mail,givenName,surname,id")
           .GetAsync();

        while (users.Count > 0)
        {
            allUsers.AddRange(users);
            if (users.NextPageRequest != null)
            {
                users = await users.NextPageRequest
                    .GetAsync();
            }
            else
            {
                break;
            }
        }
        return allUsers;
    }

I am using graph client library

The above code did not work for me without adding a call to 'CurrentPage' on the last line.
Sample taken from here.

        var driveItems = new List<DriveItem>();
        var driveItemsPage = await graphClient.Me.Drive.Root.Children.Request().GetAsync();
        driveItems.AddRange(driveItemsPage.CurrentPage);
        while (driveItemsPage.NextPageRequest != null)
        {
            driveItemsPage = await driveItemsPage.NextPageRequest.GetAsync();
            driveItems.AddRange(driveItemsPage.CurrentPage);
        }
