I’m trying to get url of variants from a background service.  
variant.GetUrl always return with exception.  
When checked in detail, its from UrlServiceImpl,  
\_routeRequestLookupInfoAccessor.RouteRequestLookupInfo.IsInAdministration is causing exception as  
RouteRequestLookupInfo is null.

Is there any other way to get variant url?

Litium version: 7

Are you sending in an existing variant and setting the ProductUrlArgs from your implementation of `Litium.Accelerator.Mvc\App_Start\UrlServiceDecorator.cs`?

Yes. An existing variant. ProductUrlArgs have all the details, except websitesystemid (Its Guid.Empty) and Category(its null)  
On decorator, the first line is  
var url = \_parent.GetUrl(variant, args); which is returning exception

Please, apply the released 7.2.0 version, it should be fixed in that version.
