WSO2 ESB Message Processor: Did not receive a javax.jms.ObjectMessage - api

Question

I inserted some json content in a queue of WSO2 Message Broker using an API of WSO2 ESB:
<?xml version="1.0" encoding="UTF-8"?>
<inSequence xmlns="http://ws.apache.org/ns/synapse">
<property name="Accept" scope="transport" type="STRING" value="application/json"/>
<call>
<endpoint>
<http method="GET" uri-template="http://localhost:9769/services/orderApi/orders"/>
</endpoint>
</call>
<iterate continueParent="true" expression="//orders/order">
<target sequence="insertOrdersMQ"/>
</iterate>
<respond/>
</inSequence>
In this API, I iterated at the json response of the endpoint and inserted the orders in one Message Broker's queue using this sequence:
<?xml version="1.0" encoding="UTF-8"?>
<sequence name="insertOrdersMQ" xmlns="http://ws.apache.org/ns/synapse">
<log level="custom">
<property name="Log: " value="Inserting order on queue"/>
</log>
<property name="OUT_ONLY" value="true"/>
<property name="FORCE_SC_ACCEPTED" scope="axis2" value="true"/>
<send>
<endpoint>
<address uri="jms:/orders_mb?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.wso2.andes.jndi.PropertiesFileInitialContextFactory&java.naming.provider.url=repository/conf/jndi.properties&transport.jms.DestinationType=queue"/>
</endpoint>
</send>
</sequence>
Then, I created a Message Processor at WSO2 ESB, because I want to consume these messages on orders_mb queue and use then in another sequence. Here is the code of the Message Store and Message Processor:
<messageStore name="orders_Store" class="org.apache.synapse.message.store.impl.jms.JmsStore" xmlns="http://ws.apache.org/ns/synapse">
<parameter name="java.naming.factory.initial">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
<parameter name="java.naming.provider.url">repository/conf/jndi.properties</parameter>
<parameter name="store.jms.destination">orders_mb</parameter>
<parameter name="store.jms.JMSSpecVersion">1.1</parameter>
<parameter name="store.producer.guaranteed.delivery.enable">false</parameter>
<parameter name="store.failover.message.store.name">orders_mb</parameter>
</messageStore>
<messageProcessor name="ordersProcessor" class="org.apache.synapse.message.processor.impl.sampler.SamplingProcessor" messageStore="orders_Store" xmlns="http://ws.apache.org/ns/synapse">
<parameter name="interval">1000</parameter>
<parameter name="concurrency">1</parameter>
<parameter name="sequence">insertOrdersDB</parameter>
<parameter name="is.active">true</parameter>
</messageProcessor>
Finally, here is the sequence that the Message Processor send the message of the queue:
<?xml version="1.0" encoding="UTF-8"?>
<sequence name="insertOrdersDB" xmlns="http://ws.apache.org/ns/synapse">
<log level="full">
<property name="Log: " value="Removing order from queue"/>
</log>
</sequence>
When I call the API resource to insert the orders in queue, it works. However, when the Message Processor consume then, it logs out
[2017-07-13 10:06:34,856] WARN - JmsConsumer [orders_mb-C-1]. Did not receive a javax.jms.ObjectMessage
I don't know what went wrong, and I saw this question that asks about the same problem, however, I already inserted the properties that are mandatory and it not worked here yet.

Try using the call mediator in blocking mode.
