Geometry Shader never worked

[625673575]

any pass create with gsEntry would result in, I have almost check all the details.
GFX call 'encoder->drawIndexed(indexCount, startIndexLocation, baseVertexLocation)' failed with error

Falcor uses geometry shaders in the LightCollection build step, so there is at least some code that exercises them. Not sure if the issue is related to the indexed draw call, did you try with a non-indexed one? Also, did you enable debug layers to see if there is anything that would explain the failure?
