The property serializer is declared read-only in IQ2i\DataImporter\DataImporter.

    }

    {
        $this->processor->begin(MessageFactory::create($this->reader));

        foreach ($this->reader as $data) {

                $this->reader,
                $this->reader->isDenormalizable() ? $this->serializeData($data) : $data

                0 === $this->reader->index() % $this->processor->getBatchSize() || $this->reader->index() === $this->reader->count()

The method getBatchSize() does not exist on IQ2i\DataImporter\Processor\ProcessorInterface. It seems like you code against a sub-type of IQ2i\DataImporter\Processor\ProcessorInterface such as IQ2i\DataImporter\Processor\BatchProcessorInterface.

            )) {
                $this->processor->batch(MessageFactory::create($this->reader));

The method batch() does not exist on IQ2i\DataImporter\Processor\ProcessorInterface. It seems like you code against a sub-type of IQ2i\DataImporter\Processor\ProcessorInterface such as IQ2i\DataImporter\Processor\BatchProcessorInterface.

            return $serializer->denormalize($data, $this->reader->getDto());

It seems like $this->reader->getDto() can also be of type null; however, parameter $type of Symfony\Component\Serializer\Serializer::denormalize() does only seem to accept string, maybe add an additional type check?

        } catch (\Exception $exception) {
            throw new \InvalidArgumentException('An error occurred while denormalizing data: '.$exception->getMessage(), $exception->getCode(), $exception);

The method archive() does not exist on null.

        } catch (IOException $ioException) {
            throw new IOException('An error occurred while archiving file: '.$ioException->getMessage());
        }
