Can not compile for 5.0.3 Material->GetEditorOnlyData(); does not exist

[eibonscroll]

	auto EditorOnly = Material->GetEditorOnlyData();
	EditorOnly->ExpressionCollection.AddExpression(Expression);
	EditorOnly->BaseColor.Expression = Expression;

I am getting the error that GetEditorOnlyData does not exist in UMaterial.

I was on version 5.0.3. Checking with 5.2.0
