FamilyType.CompoundStructureLayers getting null values for width

I used FamilyType.CompoundStructureLayers nodes to output the layer thicknesses of the wall materials. This has always worked so far. But now I get the value " null " and I don’t understand why. Does anyone here have experience or advice?

Hi @lavinia.l,

If you’re using Revit 2022, Clockwork isn’t yet updated for this version.
A workaround :
