When I run the code everything looks fine, but in the F12 console window I see many 404 errorsm stating that tiles cannot be found. What is causing all of these errors?

When you add a internet tile map, by default, the layer is assumed to be world wide. The 404 errors you see are because there are no tiles for large regions of the world.

When a 404 is encountered, the engine "cuts" the tile tree at that point, no longer requesting children of the tile that was not found.

A MapDesc contains bounds and setting the geographic bounds of the MapDesc should solve the issue.
