1. A concise explanation of the problem you're experiencing.
Until Cesium 1.43 I was able to set billboard's source to SVG.
Now I get an error:
Error loading image for billboard: [object Event]
I'm using latest Chrome v65.
2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.
var billboards = scene.primitives.add(new Cesium.BillboardCollection());
position : Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883, 150000),
image : ‘https://raw.githubusercontent.com/google/material-design-icons/master/social/svg/production/ic_cake_48px.svg’
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
I need to draw display SVG for an entity.
4. The Cesium version you're using, your operating system and browser.
Windows 7 & Windows 10, Cesium 1.43, Chrome 65
