Gismo OSM 3D road runtime error (missing member exception)

Hi fellas,

As for now I have no exp. in reading code languages and recently I interacted a problem while using GISMO plugin.

The error component throws:

  1. Solution exception:‘NoneType’ object has no attribute ‘IsClosed’
    Looking for tips to start from somewhere to solve this…

P.S how to convert attached screenshots into embedded thumbnails?

Try and look at what you have going into the _Shapes input.
You can use the Closed component to check if your polylines are closed and filter out any open polylines - use Dispatch based on the True/False Closed test. That might be what’s causing the error.
