Aha,I find why. This is bug for Uniform Volume node.
Default , This channel should be disable if you don't check Enable Displacement Map Channel.
But original node they have a mistake.
What ever you use or not this channel, Displacement Bound always want a value.
So easy to fix it.
1.right click in this material node.
2.find Displacement Bound(Vm_displacebound)
3.Use {enableDispMap==0 enableNoise==0} replace old expression
4.Done.
