我正在尝试使用XML转换为BAPI对象将XML转换为BAPI对象。我测试连接并且它成功了。在点击SAP时遇到以下错误：

我的配置如下：
连接器参考
<sap:connector name="SAP" jcoAsHost="${SAPHost}" jcoUser="${user}" jcoPasswd="${password}" jcoSysnr="${SAPSystemNumber}" jcoClient="${SAPClient}" jcoLang="${loginLanguage}" validateConnections="true" doc:name="SAP"/>
<sap:xml-to-function xmlVersion="2" name="XML_to_SAP_Function__BAPI_" doc:name="XML to SAP Function (BAPI)"/>
SAP Outbound ：
<sap:outbound-endpoint exchange-pattern="request-response" connector-ref="SAP" type="function" functionName="*******" xmlVersion="2" outputXml="true" responseTimeout="10000" transformer-refs="XML_to_SAP_Function__BAPI_" doc:name="SAP"/>
我是SAP mule的新手。请帮助我可能的原因。
我使用的版本是最新版本。

启用JCO跟踪，以便找到问题所在
要在连接器级别启用跟踪，请执行以下步骤：
将属性jcoTrace设置为true，或者提供值为1的扩展JCo属性jco.client.trace或jco.server.trace。
在Mule ESB启动时为-Djco.trace_level = N提供值。 JCo提供从0到10的跟踪级别。跟踪数据量随选定的跟踪级别而增加。每个跟踪级别还包含来自较低跟踪级别的所有跟踪数据。有关跟踪数据的详细信息，请参阅下表。如果您使用具有大量JCo调用和传输内容的高JCo跟踪级别，请确保有足够的磁盘空间可用。默认值为0.

为了获得一些上下文，您使用的是什么具体版本的SAP连接器，JCO库，Anypoint Studio和Mule Runtime？
另外，您是否可以提供Mule App的完整XML示例，包括您正在执行的转换（“XML_to_SAP_Function__BAPI _”）？
