ProjectResource Not Found Error in Project Server

Question

Hi,
I've been trying to remove a resource from project given the project resource has no assignments using the following code
            projContext.Load(projContext.Projects);
            projContext.ExecuteQuery();
            PublishedProject pp = projContext.Projects.GetByGuid(new Guid("0dbf7918-5609-e311-b791-1078d24a5e38"));
            projContext.Load(pp);
            projContext.ExecuteQuery();     
            DraftProject dp = pp.CheckOut();    
            DraftProjectResource dpr = dp.ProjectResources.GetByGuid(new Guid("e59a4729-0b03-e311-b791-1078d24a5e38"));
            projContext.Load(dpr);
            projContext.ExecuteQuery();
            DraftProjectResourceCollection resoColl = dp.ProjectResources;    
            Console.WriteLine(dpr.Id +""+dpr.Name);         
            resoColl.Remove(dpr);
            try
                QueueJob qJob = dp.Update();
                qJob = dp.Publish(false);
                JobState jobState = projContext.WaitForQueue(qJob, 30);
                if (jobState == JobState.Success)
                    Console.WriteLine("\nResource replacement Successful!");
                else
                    Console.WriteLine("\nThere is a problem in the queue. Timeout is
{0} seconds.", 30);  
when i execute this code, I get an error which says
PJClientCallableException: ProjectResourceNotFound
ProjectResourceNotFound
column = RES_UID
Am i missing something?
Thanks & Regards,
Varun

Divyang,
I am not a programmer, but I think the obvious check is to make sure that the resource you are trying to remove is actually in the project scheudle.
Another item to check is whether the resource is a LOCAL resource instead of an ENTERPRISE resource.
