使用Drupal Connector的Mule錯誤「找不到變壓器」

我想用http://www.mulesoft.org/connectors/drupal-connector的Drupal雲連接器嘗試示例。使用Drupal Connector的Mule錯誤「找不到變壓器」

但是，當我去

http://localhost:8081/drupal/node/create?title=test

創建一個新的文章，這是瀏覽器的響應：

Could not find a transformer to transform "SimpleDataType{type=java.lang.String, mimeType='*/*'}" to "CollectionDataType{type=java.util.List, itemType=java.lang.Object, mimeType='*/*'}".. Message payload is of type: String

那從MuleStudio控制檯輸出：

}

那在我的XML配置：

<?xml version="1.0" encoding="UTF-8"?> 
<mule ....> 
<drupal:config name="Drupal" username="dba" password="****" server="locahost" apiUrl="/service/rest" taxonomyTermEndpoint="taxonomy-term" taxonomyVocabularyEndpoint="taxonomy-vocabulary" doc:name="Drupal" > 
    <drupal:connection-pooling-profile initialisationPolicy="INITIALISE_ONE" exhaustedAction="WHEN_EXHAUSTED_GROW"/> 
</drupal:config> 
<flow name="drupal-esbFlow1" doc:name="drupal-esbFlow1">

       <drupal:und ref="#[payload]"/> 
      </drupal:body> 
     </drupal:node> 
    </drupal:create-node> 
    <json:object-to-json-transformer doc:name="Object to JSON"/> 
</flow>

如果我從配置

<drupal:body> 
    <drupal:und ref="#[payload]"/> 
</drupal:body>

它的工作原理去除這一部分。但這很棘手，因爲mule將這部分自動添加到配置中。

編輯：它只適用於我不使用REST服務器的身份驗證，以及如果我給匿名用戶添加節點的權利。這是Drupal Connector中的一個Bug嗎？
