It seems like $this->serializer->normalize($mapping) can also be of type integer and string and boolean and double; however, parameter $mapping of AmaTeam\ElasticSearch\Mapping\Normalizer::normalizeArray() does only seem to accept array, maybe add an additional type check?

        if ($normalized['type'] === TypeEnum::ROOT) {
            unset($normalized['type']);
        }
        return $normalized;
    }

    private function normalizeArray(array $mapping): array
    {
        $type = $mapping['type'];
        $target = ['type' => Strings::camelToSnake($type)];
        foreach (TypeEnum::getParameters($type) as $parameter) {
            if (isset($mapping[$parameter])) {
                $target[Strings::camelToSnake($parameter)] = $mapping[$parameter];
            }
        }
        $key = 'properties';
        if (!empty($target[$key])) {
            $target[$key] = array_map([$this, 'normalizeArray'], $target[$key]);
        } else {
            unset($target[$key]);
        }
        return $target;
    }
}
