我正在尝试通过 wso2 esb 序列从 wso2 数据服务中获取一些数据,如下所示
<sequence xmlns="http://ws.apache.org/ns/synapse" name="ConcurGetSAEExtractFlow">
<log level="custom">
<property name="Debugging" value="ConcurGetSAEExtractFlow" />
</log>
<xslt key="GetConcurSAE_Extract_Transformation" />
<property name="post-data-service-sequence" value="ConcurTransformSAEExtractFlow" />
<property name="OUT_ONLY" value="false" />
<send receive="DataServiceInvocationErrorFlow">
<endpoint key="ConcurDataServiceEndpoint" />
</send>
<description />
</sequence>
xslt 转换 GetConcurSAE_Extract_Transformation 如下
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dat="http://ws.wso2.org/dataservice" xmlns:fn="http://www.w3.org/2005/02/xpath-functions" version="1.0">
<xsl:template match="/">
<xsl:element name="dat:GetConcurSAEExtract">
</xsl:element>
</xsl:template>
</xsl:stylesheet>
正如所见,没有提供服务的输入映射,并且提供了输出映射。我已经在 wso2 dss "try this service" 中测试了该服务,它运行良好。但是,当我尝试通过代理通过 wso2 esb 运行它时,我收到以下错误块

我无法找出导致这种错误的问题所在。请如果有人对此有任何想法。
