Thanks in advance.

I’m using it like an “Error Catcher”:

You are feeding a single bool so the node is pulling the one false test not 9 tests and therefore gives you the single list depth. Set the lacing in the test node to longest. 🙂

You’ll most likely also want to match your list structures between true and false. You can do this by chopping your polycurve list by a length of one (1).
