It seems like you code against a concrete implementation and not the interface League\Event\EventInterface as the method getMap() does only exist in the following implementations of said interface: ApiClients\Foundation\Events\CommandLocatorEvent.

    }

    private static function createTransport(
        ContainerInterface $container,
        LoopInterface $loop = null,
        array $options = []
    ): TransportClient {
        return TransportFactory::create($container, $loop, $options);

$container of type object<Interop\Container\ContainerInterface> is not a sub-type of object<League\Container\ContainerInterface>. It seems like you assume a child interface of the interface Interop\Container\ContainerInterface to be always present.

    }

    private static function createHydrator(ContainerInterface $container, array $options = [])
    {
        if (isset($options[Options::HYDRATOR]) && $options[Options::HYDRATOR] instanceof Hydrator) {
            return $options[Options::HYDRATOR];
        }

        if (!isset($options[Options::HYDRATOR_OPTIONS])) {
            throw new \Exception('Missing Hydrator options');
        }

        return HydratorFactory::create($container, $options[Options::HYDRATOR_OPTIONS]);

$container is of type object<Interop\Container\ContainerInterface>, but the function expects a array.

The call to Factory::create() has too many arguments starting with $options[\ApiClients\Foundation\Options::HYDRATOR_OPTIONS].
