WSO2数据服务未绑定输入

我试图创建一个简单的数据服务，在数据库中插入一个具有以下定义的条目：

<data name="RESTLoggerDataService" serviceNamespace="" transports="http https">
  <config id="default">
    <property name="driverClassName">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
    <property name="url">jdbc:sqlserver://SERVER:1433;databaseName=DB</property>
    <property name="username">user</property>
    <property name="password">pass</property>
  </config> 
  <query id="CreateLog" useConfig="default">
    <sql>INSERT INTO Log (Date, Username, ServiceID) VALUES (?,?,?)</sql>
    <param name="Date" paramType="SCALAR" sqlType="STRING" type="IN" ordinal="1"/>
    <param name="Username" paramType="SCALAR" sqlType="STRING" type="IN" ordinal="2"/>
    <param name="ServiceID" paramType="SCALAR" sqlType="STRING" type="IN" ordinal="3"/>
  </query>
  <resource method="POST" path="Log">
    <call-query href="CreateLog">
      <with-param name="Date" query-param="Date"/>
      <with-param name="Username" query-param="Username"/>
      <with-param name="ServiceID" query-param="ServiceID"/>
    </call-query>
  </resource>
 </data>

使用以下XML：

<_postlog>
    <Date>2020-09-15 09:06:00.000</Date>
    <Username>KIRBJJ</Username>
    <ServiceID>WA233</ServiceID>
</_postlog>

但要收回以下内容：

输入参数似乎没有正确绑定。有人知道我做错了什么吗？

我用MySQL创建了一个类似的数据服务，没有遇到任何问题。请你试试下面的，看看有没有变化。通过如下添加名称空间来更改负载，并尝试相同的中介

<p:_postlog xmlns:p="http://ws.wso2.org/dataservice">
    <xs:Date xmlns:xs="http://ws.wso2.org/dataservice">2020-09-15 09:06:00.000</xs:Date>
    <xs:Username xmlns:xs="http://ws.wso2.org/dataservice">KIRBJJ</xs:Username>
    <xs:ServiceID xmlns:xs="http://ws.wso2.org/dataservice">WA233</xs:ServiceID>
</p:_postlog>

如果这不起作用，请启用wire logs并确认将正确的有效负载传递给数据服务
