It seems like $this->curriculumVitae->getCurriculumViateArray() targeting FabienCrassat\CurriculumVitaeBundle\Entity\CurriculumVitae::getCurriculumViateArray() can also be of type null; however, FabienCrassat\CurriculumVitaeBundle\Controller\DefaultController::setParameters() does only seem to accept array, maybe add an additional type check?
