This comes from sofa prefab obviously when applied to class ServoMotor(SofaObject)

I think addNewData is the old SofaPython2 API, while we now use SofaPython3. Could you try to use addData instead? The doc is here: https://github.com/sofa-framework/SofaPython3/blob/master/bindings/Sofa/src/SofaPython3/Sofa/Core/Binding_Base_doc.h#L125

I think the problem comes from splib like for issue #13. Need investigation

[alxbilger]

Can you try if SofaDefrost/STLIB#92 fixes the problem?
