private LoggerInterface $logger;

private RuleRepositoryInterface $ruleRepository;

public function __construct(

LoggerInterface $logger,

RuleRepositoryInterface $ruleRepository

) {

$this->logger = $logger;

$this->ruleRepository = $ruleRepository;

}

public function getRuleData(int $ruleId): ?RuleInterface

{

try {

return $this->ruleRepository->getById($ruleId);

} catch (\Exception $e) {

$this->logger->error(__('Error fetching rule: %1', $e->getMessage()));

return null;

}
