WSO2 ESB:AxisFault:无协议

WSO2 ESB 4.6.0中的以下代理有问题：

<proxy name="GetCapacity" transports="http https" startOnLoad="true" trace="disable">
  <target>
     <inSequence>
        <xslt key="conf:ManageWorkforce/xslt/GetCapacity_Request.xsl"/>
        <send>
           <endpoint key="Capacity"/>
        </send>
     </inSequence>
     <outSequence>
        <filter xpath="get-property('FAULT')">
           <then>
              <log level="full" separator=",">
                 <property name="trace" value="-------- FAULT ---------"/>
              </log>
              <xslt key="conf:ManageWorkforce/xslt/SoapFaultToStandardHeader.xsl"/>
              <header name="To" expression="get-property('ReplyTo')"/>
           </then>
           <else>
              <xslt key="conf:ManageWorkforce/xslt/GetCapacity_Response.xsl"/>
           </else>
        </filter>
        <send/>
     </outSequence>
     <faultSequence>
        <log level="full" separator=",">
           <property name="trace" value="-------- FAULT SEQUENCE -------"/>
        </log>
        <property name="RESPONSE" value="true"/>
        <header name="To" expression="get-property('ReplyTo')"/>
     </faultSequence>
  </target>
</proxy>

当我使用soapUI调用它并且服务抛出SoapFault（FAULT属性为TRUE）时，WSO2中会发生以下错误：

我做错了什么？

根据错误，似乎是“to”标题不正确。请您尝试删除“收件人”标题并查看。在您的配置中，已使用“ReplyTo”属性添加“To”标题。因此，请将以下内容添加到故障序列中

<header name="To" action="remove"/>

此外，最好启用调试日志，以解决问题。这将在线路上显示消息。请从log4j.properties文件中启用以下两个属性，该文件位于/repository/conf目录

log4j.logger.org.apache.synapse.transport.nhttp.wire=DEBUG log4j.logger.org.apache.synapse.transport.nhttp.headers=DEBUG

在答案中添加更多内容，您已经从“ReplyTo”中复制了“To”标题。您可以按如下方式记录“ReplyTo”的值，以检查它是否确实不正确

<log level="custom"><property name="RelyTo" expression="get-property('ReplyTo')"/></log>

谢谢您的回答。我已将

删除到

，但现在发生了以下情况：

org.apache.axis2.AxisFault:To和MessageContext.TRANSPORT\u OUT属性都为空，因此无处发送

Hmm我们是否验证，抱歉。。我在回答中又加了一些。请查收。最好验证您的“ReplyTo”值。或者从out序列中删除属性，然后查看。我已删除。错误与上面第一条注释中描述的相同。SoapFault之后：

To=http://www.w3.org/2005/08/addressing/anonymous，From=，Action=，ReplyTo=，FaultTo=

。然后，我将

删除到

和
