Karamba - Optimize Cross Section giving error

Grasshopper Karamba3D

Hi,
I updated to the current version and suddenly the Optimize Cross Section Component does not work. I changed all the "Old"components, no change. Error message: Input item number 0: element is no string or integer. Does anyone have a clue how to fix it and to make the analysis definiton run?

The input for “ElemIDs” should be a text or string, and not the element itself
