Error creating RectangleGeometry

I’m getting an error creating a RectangleGeometry. Has anyone ever seen this?

DataCloneError: Failed to execute ‘postMessage’ on ‘Worker’: An object could not be cloned.

Error: Failed to execute ‘postMessage’ on ‘Worker’: An object could not be cloned.

I’m specifying a Rectangle, vertexFormat and stRotarion. Pretty much the same RectangleGeometry in the Geometry and Appearances demo.

I figured it out. I was creating a new vertexFormat instead of using Cesium.EllipsoidSurfaceAppearance.VERTEX_FORMAT.

Hi Scott,

I am trying to draw PolygonGeometry on Cesium Map. I am also facing the same DataCloneError what you get in RectangleGeometry. I used the Cesium.EllipsoidSurfaceAppearance.VERTEX_FORMAT while creating PolygonGeometry.

Could you please help me in which case we get this error in Cesium.

Thanks,
Raghu.
