Answer 1

In my case, I was passsing all models 'Users' to column and it wasn't mapped correctly, so I just passed 'Users.Name' and it fixed it.

var data = db.ApplicationTranceLogs 
             .Include(q=>q.Users)
             .Include(q => q.LookupItems) 
             .Select(q => new { Id = q.Id, FormatDate = q.Date.ToString("yyyy/MM/dd"), ***Users = q.Users,*** ProcessType = q.ProcessType, CoreProcessId = q.CoreProcessId, Data = q.Data }) 
             .ToList();

var data = db.ApplicationTranceLogs 
             .Include(q=>q.Users).Include(q => q.LookupItems) 
             .Select(q => new { Id = q.Id, FormatDate = q.Date.ToString("yyyy/MM/dd"), ***Users = q.Users.Name***, ProcessType = q.ProcessType, CoreProcessId = q.CoreProcessId, Data = q.Data }) 
             .ToList();
