Error Messages

[AZZ-Th]

hello I recently discovered the feature " Sverchok". I have problems on version 4.2 that I do not have on version 4.0. I want to reproduce what I did on the old versions only I have error messages that I can’t understand. No doubt I am not using the correct procedure or are there new nodes that allow to make work? Someone could help me solve this problem ?

it is about "data", " Value Error", "Inomogeneous part", as well as what is present on the attached image

this one is ok ( 4.0)

this one does'nt work ( 4.2 )

Is the same when I work with Random Vector

this one is ok ( 4.0)

this one does'nt work ( 4.2 )

inset special uses numpy heavily, there might be some updates in the numpy that ships with Blender between those two releases.

and the first screenshot tells me that the add_mesh_extra_object library is missing from 4.2's python/bpy scripts ( it might not be in the standard installation anymore? )
