The function React\EventLoop\Factory::create() has been deprecated: 1.2.0 See Loop::get() instead.

MessengerFactory::child($loop, ArgvEncoder::decode($arguments))->done(function (Messenger $messenger) use ($loop) {

The method done() does not exist on React\Promise\PromiseInterface. It seems like you code against a sub-type of said class. However, the method does not exist in React\Promise\CancellablePromiseInterface. Are you sure you never get one of those?

The import $loop is not used and could be removed.

    $messenger->registerRpc('hello', function (Payload $payload, Messenger $messenger) {

The parameter $messenger is not used and could be removed.

The parameter $payload is not used and could be removed.
