I'm trying to send data between two sessions using data queue. Here is how I tried to do that:

First Matlab instance creates PollableDataQueue and saves it in matfile
Second instance reads it and sends data object to the first one

However such approach results in an error when I send a message:

Struct contents reference from a non-struct array object.
Error in parallel.internal.pool.AbstractDataQueue/send (line 135)
                if obj.Session.isSessionRunning
Error in QueueManager/send_request (line 33)
            request_queue.send(task);
Error in TaskSender/get_latest_max (line 15)
            obj.queue_manager.send_request(task);

Is there a way to achieve such communication between Matlab sessions?

I also get a warning when loading queue from matfile:

Warning: While loading an object of class 'parallel.pool.PollableDataQueue':
To send and receive messages there must be a pool.
