amphp/parallel-functions in Symfony

Question

/** @var array<ServiceInterface> */
    protected $services;

    public function __construct(array $services)
    {
        $this->services = $services;
    }

    public function checkRkoDuplicates(Payload $payload)
    {
        $services = $this->services;

        try {
            $results = Promise\wait(parallelMap($services, function (ServiceInterface $service) use ($payload) {
                return $service->exchange($payload); // ?string
            }));
        } catch (MultiReasonException $exception) {
            foreach ($exception->getReasons() as $reason) {
                var_dump($reason->getMessage());
            }

            return null;
        }

        return $results;
    }

If in Symfony I use APP_ENV = dev everything works. If APP_ENV = prod then I get error The given data could not be serialized: Serialization of 'Closure' is not allowed .

Why it happens? How to make it work?

Answer 1

Monolog tried to write logs from services to prod.log. But excluded_http_codes: [404, 405] was breaking the entry. Since the service logs are stored separately, I disabled the logs from services in prod.log
