Mule - '验证的表达式为false'错误

我正在使用Mule IDE尝试SiteId和Sku使用Magento连接器获取GetProduct。

这是我的流程: 它以JSON格式从队列接收params(SiteId和Sku):

 <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>

异常堆栈是:

  1. 验证的表达式为false(java.lang.IllegalArgumentException) org.apache.commons.lang.Validate:181(null)
  2. 无法调用getProduct。消息有效内容的类型为:String(org.mule.api.MessagingException) org.mule.devkit.processor.DevkitBasedMessageProcessor:133(http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/MessagingException.html
  3. Root异常堆栈跟踪:

    任何建议?

答案 0 :(得分:2)

source code显示了这一点:

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

基本上指的是magento:get-product元素至少需要magento:attributes-namesmagento:additional-attribute-names子元素。

请参阅此处的API文档:http://mulesoft.github.io/magento-connector/2.2.0/mule/magento-config.html#get-product
