        $this->stepService->setCurrentSubstepDefinition($substepDefinition);

It seems like $substepDefinition defined by $this->service->findFirstSubstepDefinition($this->currentStep) on line 82 can be null; however, Romm\Formz\Form\FormObject\Service\FormObjectSteps::setCurrentSubstepDefinition() does not accept null, maybe add an additional type check?
