I was able to run the example thanks to your fix. If you're interested, I have some suggestions that might improve your UX.
The "App Examples" section of the documentation represents a tree similarly to the way that "Platform Policy", but the App Examples root is currently clickable which might cause some confusion.
May I suggest adding additional descriptions to the documentation? Map, for example, very helpfully provides a description for itself and its functions, but this is missing for Tiles -- what exactly is a Tile? What are some of the things that a developer might want to use the .get function for?
Thanks so much.
