The arrays themselves may be extremely large, thus they live on the server, not the client and you can't get them directly as you are trying to do. You can however use servermanager.Fetch to bring them over, but you should only do so once you have filtered them down in size a bit. Try using the threshold filter, picking out only those cells/points near the maximum, then fetching that.
