exception, id user doubleclick on the center node

I have 3D diagram
have sprint layout , so it is one node in the middle and another nodes around it

when the user double click in the centered node it throw this exception
Parameter is not valid.

I tried tor rectify the issue and I realize that it is because this line
dgView3D.CameraPosition = SourceNode.LayoutTraits(View3D.Position)

this line to stop the middle one from moving (center it to camera)
If  stopped this line exception will never come
how to fix it please

Does SourceNode.LayoutTraits contain a View3D.Position key at all when this happens?

I got a work around and the exception not happening now

I tried to give some deviation to the camera position to not be same as the centerNode (SourceNode) position
here is the code
     Dim pos As Point3D = SourceNode.LayoutTraits(View3D.Position)
           dgView3D.CameraPosition = New Point3D(pos.X, pos.Y, pos.Z + 0.0001)

now it works but I think you need to fix something there or at least not the exception happens

The CameraPosition setter does not throw exceptions if I just assign that point. What is shown at the top of the callstack when you get the exception?

What are the CameraRotation values at that point?

Could you check if the version below throws an exception?
https://mindfusion.eu/_beta/fcnet_3dtest.zip

If it does, can you see any "view3d:" messages logged in the debug output window?
