passing object in rpyc fails

Question

I am trying to pass an object as a paramater using RPyC from the client to the server. But the server is unable to access the object and I receive an AttributeError.

Server Code:

class AgentService(rpyc.Service):
  def exposed_func(self, obj):
    return obj.name

client code

self._conn = connect(agent_host, agent_port, config = {"allow_public_attrs" : True})
return self._conn.root.func(obj)

returns: AttributeError: cannot access 'name'.

I am using RPyC services and accoding to the website, this should work.

Any ideas?

The config dict needs to be adjusted on the client side and the server side.

The main value to change is allow_public_attrs : True if only public variables need to be accessed or allow_all_attrs : True if private and protected variables and methods need to be accessed (i.e, those that start with '_').

On the client side, the connection code is written as in the question above and on the server code as follows:

server = ThreadedServer(MyService, port = 12345,
                        protocol_config = {"allow_public_attrs" : True})
