wso2esb和wso2dss中的错误

我正在使用wso2esb 4.7.0和wso2dss 3.0.0

 <query id="trial_query" useConfig="default">
      <sql>update muser set username=? where userid=?</sql>
      <param name="username" ordinal="1" sqlType="STRING"/>
      <param name="userid" ordinal="2" sqlType="BIGINT"/>
   </query>

 <operation name="trial_op">
      <call-query href="trial_query">
         <with-param name="username" query-param="username"/>
         <with-param name="userid" query-param="userid"/>
      </call-query>
   </operation>

现在，问题是当我在send mediator ESB中添加序列时抛出一个错误，如下所示：

为什么会出现错误？他们在send mediator期间是否对soap格式有任何问题，或者我必须在esb配置中添加一些属性？我应该如何解决此问题？请让我知道。

检查下面的curl-request curl-v-H“Content Type:application/json”POST-d'{“username”：“Harry”，“userid”：“347367127872701992”}'谢谢Dakshika..使用这个curl命令和我在问题中提到的curl命令，它在第一个序列中运行良好..但是当我尝试在第一个序列中添加第二个序列时，出现了相同的问题。。

 <property name="messageType" value="application/json" scope="axis2"></property>
   <property xmlns:ns="http://org.apache.synapse/xsd" xmlns:s="http://ws.wso2.org/dataservice" name="username" expression="get-property('username')" scope="default" type="STRING"></property>
   <log>
      <property name="username" value="UPDATED SUCCESSFULLY"></property>
   </log>
   <send></send>

  curl -v -H "Accept:application/json" -H "Content-Type:application/json"  -d '{"username":"Harry","userid":"347367127872701992"}' http://youtility-desktop:8282/services/capp1
