ListFolderContinueAsync request throw an error

I am using following Code.

 public class SyncOperation
    {
        static DropboxClient dbx = new DropboxClient("MyAccessToken");
        public async void applyChanges()
          {           
            ListFolderContinueArg lfg = new ListFolderContinueArg("AAFm_IAxqFFyTAcg43BDIcEmCMf8fFwXGJ6GaxjXJIebJjO6hAFZw73laDO743HI8KlVWGu-INc6tmcm5qKjILbUZJOt8X8i1Ifnjc1g6G3D_W5HATTXeiVOcLAuhhSESPuZrF1QuhwYpo4_4iZ72IeL");
            var list = await dbx.Files.ListFolderContinueAsync(lfg);                    

            Console.WriteLine("Change List count : " + list.Entries.Count);
            foreach(var i in list.Entries)
            {
                Console.WriteLine(i.Name);
            }
        }
    }

I have generate Cursor from this link and passed in the parameter. It works fine when I have test that on this link. But in my code it throws "Invalid Cursor" exception.
