Error in receiving the message from the RabbitMQ broker Siddhi as java library

Question

I'm doing an android app with Siddhi. I'm using rabbitmq to communication between the app and a server app. But i can't retrieve the message from the broker.

dependencies{
  ....
 implementation ('io.siddhi.extension.io.rabbitmq:siddhi-io-rabbitmq:3.0.6'){
        transitive = false
    }


    implementation ('io.siddhi.extension.map.json:siddhi-map-json:5.0.7'){
        transitive = false
    }

implementation 'com.fasterxml.jackson.core:jackson-databind:2.11.0' //=> I add this line to work the siddhi map json dependency

}

When I try to retrieve the message from the broker i have the following error:

ERROR io.siddhi.core.stream.input.source.Source  - Error on 'communicationServer'. Error in receiving the message from the RabbitMQ broker in io.siddhi.extension.map.json.sourcemapper.JsonSourceMapper@a8b0f11 Error while connecting at Source 'rabbitmq' at 'inputStream'.

Here is my siddhi query:

  siddhiServer = "@app:name('communicationServer') " +
                "@source(type='rabbitmq'," +
                "uri='amqp://tfgServer:tfgServer@192.168.1.158:5672'," +
                "exchange.name='prueba'," +
                "queue.name='cola_receptor2',"+
                "@map(type='json')) " +
                "define stream inputStream(result int); " +
                "from inputStream select * insert into outputResult";

        siddhiRuntimeServer = siddhiManager.createSiddhiAppRuntime(siddhiServer);

        siddhiRuntimeServer.start();
        siddhiRuntimeServer.addCallback("outputResult", new StreamCallback() {
            @Override
            public void receive(Event[] events) {

                EventPrinter.print(events);
               
            }
        });

Anyone knows what am i doing wrong??
