Clockwork: List.ReplaceEmptyLists is not working

Hello everyone,

I’m using the List.ReplaceEmptyLists node from the Clockwork package. It worked before but now it seems that it’s not working anymore. I have to replace them because I want to flatten the list but keep the hierarchy, so when I replace it by a string the hierarchy will be the same after flattening.

I already tried setting the lacing to longest but it still won’t work

I hope someone can help me.
