WSO2 ESB: Erro inesperado de caractere ao enviar JSON ao serviço de proxy
Estou tentando recuperar dados do Facebook usando o WSO2 Facebook Connector no WSO2 ESB 4.9.0. Forneci a configuração de proxy abaixo.
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="facebook_getFeed"
transports="https,http"
statistics="disable"
trace="disable"
startOnLoad="true">

<inSequence onError="fault">

<property name="userId" expression="json-eval($.userId)"/>
<property name="numOfFeeds" expression="json-eval($.numOfFeeds)"/>

<respond/>
</inSequence>
<outSequence>
<property name="messageType" value="application/json" scope="axis2"/>
<send/>
</outSequence>
</target>
<description/>
</proxy>
O problema que estou tendo é que sempre que faço uma solicitação POST ao serviço, o tempo limite é excedido. Verificando os logs de erro do ESB, parece que houve um "Erro ao criar o fluxo de transmissão".

Referindo-me à configuração do proxy acima, eu tenho um mediador de log que realmente imprime com êxito a carga útil JSON, o que me leva a pensar que tem algo a ver com o formatador de mensagens.
Minha configuração do formatador / construtor de mensagens no arquivo Axis2.xml é a seguinte:
<!--JSON Message Formatters-->
<messageFormatter contentType="application/json" class="org.apache.synapse.commons.json.JsonStreamFormatter"/>
<!--JSON Message Builders-->
<messageBuilder contentType="application/json" class="org.apache.synapse.commons.json.JsonStreamBuilder"/>
Tudo o resto deste arquivo é conforme a configuração padrão.
O que poderia estar errado aqui?
