            $propertyValue = $parameters[$propertyName] ?? [];
            $propertyTypeName = PropertyHelper::getTypeName($property);

            $constraints[$propertyName] = match (true) {
                $this->extractorLocator->has($property) => ArrayList::collect($propertyValue)->map(fn () => new All($this->extract($this->extractorLocator->get($property)->extract($property), $propertyValue)))->toArray(),

It seems like $this->extractorLocator->get($property)->extract($property) can also be of type null; however, parameter $className of FRZB\Component\RequestMapper\Extractor\ConstraintExtractor::extract() does only seem to accept string, maybe add an additional type check?

                ClassHelper::isNotBuiltinAndExists($propertyTypeName) => $this->extract($propertyTypeName, $propertyValue),
                default => ConstraintsHelper::fromProperty($property),
            };
        }

        return $constraints;
    }
