呼叫調解器在 WSO2 中引發錯誤

Question

當我嘗試在帶有 blocks="true" 的序列中使用 call mediator 時，它會在 send mediator 正常工作時拋出錯誤。 有人可以請強調我錯的地方。
我正在使用 WSO2 APIM 2.6.0

代碼：

<call blocking="true">
    <endpoint>
       <http method="get" uri-template="http://10.10.10.10:10/XYZ/rest/1.0/abc/{uri.var.userId}"/>
    </endpoint>
</call>             
<respond/>

我收到以下錯誤消息：

INFO {org.apache.axis2.transport.http.HTTPSender} -  Unable to sendViaGet to url[http://10.10.10.10:10/XYZ/rest/1.0/abc/USERX] {org.apache.axis2.transport.http.HTTPSender}

嘗試在呼叫調解器之前添加它。

<property name="REST_URL_POSTFIX" scope="axis2" action="remove"/>
