VTK_TRIANGLE 97 with less than three points, but VTK_TRIANGLE needs at least three points

Hello everyone,
I’d like to find intersection between two different sources. And later on apply it to a poly data that is extracted from a model node and a cube source.
I was looking for a way to do it and I found a extension: https://github.com/zippy84/vtkbool.

I also found an example that uses the extension here: https://lorensen.github.io/VTKExamples/site/Cxx/PolyData/PolyDataBooleanOperationFilter/

I am trying to test the intersection between two sphere sources, but I am getting a warning and the slicer crashes.

'Warning: In /home/anish/3D_Slicer_Code/Code_with_changes/Build/VTK/Common/DataModel/vtkPolyData.cxx, line 1021

It seems like the input polydata is corrupted. How did you generate it?
Maybe you can fix it by using Cleaner option in Surface Toolbox module.
