Hello Tuba Kumbara‌,

I think this behaviour is normal. There are natural bounds on your projection and basemap. What you can do is to set a minimum scale on your view to set a limit for the user to zoom out. You can do this in the View() object:

var view = new MapView({
  container: "viewDiv",
  spatialReference: { wkid: 31463 },
  map: map,
  zoom: 8,
  constraints: {
    minScale: 100000
  }
});‍‍‍‍‍‍‍‍‍

Thanks for the answer.

But actually i mean white spaces of top and bottom of map. There is no problem with left and right side. White spaces appears even you define minscale. Please try to move map with mouse to top or bottom continuously.

You can see white space after a while.

Tuba,

As Richard explained that is normal behavior the map with wrap around the dateline east and west but the map does not wrap around north and south. So you will encounter a bank map with you beyond the North Pole or South Pole.
