Data-Shapes Multi Input UI and ModelChecker

Hi,

I opened a script sent me by a colleague that look exactly the same as the ones showed above but I’m getting this error “expected str, got list”:

Then I downloaded the script shared here Multi Input UI, non-pointer error and it works.

I’m using data-shape 2017.10.1 and Dynamo 1.3.1

This script gives the error.
ModelChecker.dyn (26.2 KB)

Any ideas?

Thank you
Giovanni
