Where did you get that material copy code from?

Try this simple const 0 node which I just copied:

Begin Object Class=MaterialGraphNode Name=“MaterialGraphNode_2”
Begin Object Class=MaterialExpressionConstant Name=“MaterialExpressionConstant_3”
End Object
Begin Object Class=EdGraphPin Name=“EdGraphPin_2620”
End Object
Begin Object Name=“MaterialExpressionConstant_3”
MaterialExpressionEditorX=-463
MaterialExpressionEditorY=477
MaterialExpressionGuid=0E1765054CB0763FD03A4C8FD45B5D36
Material=PreviewMaterial’/Engine/Transient.M_50percent_Test’
End Object
Begin Object Name=“EdGraphPin_2620”
PinName=“Output”
PinFriendlyName=" "
Direction=EGPD_Output
End Object
MaterialExpression=MaterialExpressionConstant’MaterialExpressionConstant_3’
Pins(0)=EdGraphPin’EdGraphPin_2620’
NodePosX=-463
NodePosY=477
NodeGuid=2750A80041698FF8B965C1B2793DF2EA
End Object
