Мул - ошибка "Проверенное выражение ложно"

Я пытаюсь получить продукт по SiteId и Sku с коннектором Magento, используя Mule IDE.

Это мой поток: он получает параметры (SiteId и Sku) из очереди в формате JSON:

 <flow name="flow">
    <amqp:inbound-endpoint queueName="test" responseTimeout="10000" exchange-pattern="request-response" connector-ref="AMQPConnector" doc:name="AMQP-0-9"/>
    <byte-array-to-object-transformer doc:name="Byte Array to Object"/>
    <json:object-to-json-transformer doc:name="Object to JSON"/>
    <set-variable variableName="site" value="#[json:/site]" doc:name="siteVar"/>
    <set-variable variableName="sku" value="#[json:/sku]" doc:name="skuVar"/>
    <logger message="Gettting data from queue #[flowVars.site] and #[flowVars.sku]" level="INFO" doc:name="Logger"/>
    <magento:get-product config-ref="Magento"  doc:name="Magento" storeViewIdOrCode="#[flowVars.site]" productIdOrSku="#[flowVars.sku]"/>
</flow>

Стек исключения:

  1. Подтвержденное выражение ложно (java.lang.IllegalArgumentException) org.apache.commons.lang.Validate: 181 (null)
  2. Не удалось вызвать getProduct. Полезные данные сообщения имеют тип: String (org.mule.api.MessagingException) org.mule.devkit.processor.DevkitBasedMessageProcessor: 133 (http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/MessagingException.html) < час>

исходный код показывает следующее:

Validate.isTrue(CollectionUtils.isNotEmpty(attributeNames)
                || CollectionUtils.isNotEmpty(additionalAttributeNames));

что в основном указывает на то, что элементу magento:get-product требуется как минимум magento:attributes-names или magento:additional-attribute-names дочерний элемент.

См. Документ API здесь: http://mulesoft.github.io/magento-connector/2.2.0/mule/magento-config.html#get-product
