富民介體無效的對象類型到消息主體

Question

ERROR：豐富介體無效的對象類型將被插入到消息主體

試圖豐富消息時

，這裏是代理配置：

<proxy xmlns="http://ws.apache.org/ns/synapse" name="Database" transports="https,http" statistics="disable" trace="disable" startOnLoad="true"> 
    <target> 
     <inSequence> 
     <dblookup> 
      <connection> 
       <pool> 
        <password>1234</password> 
        <user>root</user> 
        <url>jdbc:mysql://localhost:3306/new_db</url> 
        <driver>com.mysql.jdbc.Driver</driver> 
       </pool> 
      </connection> 
      <statement> 
       <sql>select * from users where name="rik"</sql> 
       <result name="client_expiration" column="expiration" /> 
       <result name="client_id" column="id" /> 
       <result name="client_name" column="name" /> 
      </statement> 
     </dblookup> 
     <log level="custom"> 
      <property name="returned value for client_expiration is :" expression="get-property('client_expiration')" /> 
      <property name="returned value for client_id is :" expression="get-property('client_id')" /> 
      <property name="returned value for client_name is :" expression="get-property('client_name')" /> 
     </log> 
     <property name="property1" expression="get-property('client_expiration')" scope="default" /> 
     <enrich> 
      <source type="property" property="property1" /> 
      <target type="body" action="sibling" /> 
     </enrich> 
     <sequence key="getback" /> 
     </inSequence> 
    </target> 
</proxy> 

和序列配置（但不應該是這裏的問題）：

<sequence xmlns="http://ws.apache.org/ns/synapse" name="getback"> 
    <header name="To" action="remove" /> 
    <property name="RESPONSE" value="true" scope="default" /> 
    <send /> 
    <log level="full" /> 
</sequence> 

提前非常感謝！

有豐富調解員這樣，嘗試

<enrich> 
      <source type="custom" xpath="get-property('property1')"/> 
      <target type="body" action="sibling"/> 
     </enrich>
