我剛開始Mule我創建使用twitter無法調用updateStatus。消息負載的類型爲：字符串
我使用mule 3.5一個很簡單的例子，我開始與現在創建New Example Project那麼Hello world
我使用twitter和每一件事情看起來不錯，當我使用show user我得到的JSON對象，但是當我做update status我得到這個錯誤信息：
Failed to invoke updateStatus. Message payload is of type: String
這裏是我的XML
<flow name="TwitterUserID" doc:name="TwitterUserID">
<http:inbound-endpoint exchange-pattern="request-response"
host="localhost" port="8081" doc:name="HTTP"
doc:description="This endpoint receives an HTTP message." />
<object-to-string-transformer doc:name="Object to String"/>
<twitter:update-status config-ref="Twitter" doc:name="Twitter" status="This is from
Mule "/>
<json:object-to-json-transformer doc:name="Object to JSON"/>
</flow>
錯誤
