The call to VariantSuperAttributeObserver::prepareStoreViewCode() has too many arguments starting with $this->getRow().

            $this->productSuperAttributeId = $this->persistProductSuperAttribute($productSuperAttribute);

Are you sure the assignment to $this->productSuperAttributeId is correct as $this->persistProductSuperAttribute($productSuperAttribute) (which targets TechDivision\Import\Product\Variant\Observers\VariantSuperAttributeObserver::persistProductSuperAttribute()) seems to always return null.

            // initialize and save the super attribute label
            $productSuperAttributeLabel = $this->initializeProductSuperAttributeLabel($this->prepareProductSuperAttributeLabelAttributes());
            $this->persistProductSuperAttributeLabel($productSuperAttributeLabel);
