1. A concise explanation of the problem you're experiencing.

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

Hi Duke,

This has been fixed! https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/index.html?src=Hello%20World.html&label=Showcases

Make sure you clear your cache or open in a new incognito window if you’re still getting a “404 Not Found”.

Thanks for your patience!

Gaby
