Question

我的代理服务中有一个有效负载工厂中介，如下所示。

 <payloadFactory media-type="json">
            <format>{
   "EntityTypeCode":"asx",
   "SchoolId":$1,
   "Format":"json",
   "InputData":{
      "Accounts":{
         "Account":[
            {
               "UserName":$2,
               "StudentID":$3,
               "FirstName":$4,
               "LastName":$5,
               "Email":$6,
               "DOB":$7,
               "SSN":$8,
               "Password":$9,
               "GenderCode":$10,
               "Address1":$11,
               "City":$12,
               "State":$13,
               "ZipCode":$14
            }
         ]
      }
   }
}
</format>
            <args>
               <arg evaluator="xml" expression="get-property('SchoolId')"/>
               <arg evaluator="xml"
                    expression="$body/*[local-name()='Object']/*[local-name()='Payload']/*[local-name()='ID'][*[local-name()='Type']='abc']/*[local-name()='Value']/text()"/>
               <arg evaluator="xml"
                    expression="$body/*[local-name()='Object']/*[local-name()='Payload']/*[local-name()='ID'][*[local-name()='Type']='abc']/*[local-name()='Value']/text()"/>
               <arg evaluator="xml" expression="get-property('first_name')"/>
               <arg evaluator="xml" expression="get-property('last_name')"/>
               <arg evaluator="xml" expression="get-property('email_address')"/>
               <arg evaluator="xml" expression="get-property('birth_date')"/>
               <arg evaluator="xml"
                    expression="$body/*[local-name()='Object']/*[local-name()='Payload']/*[local-name()='ID'][*[local-name()='Type']='abc']/*[local-name()='Value']/text()"/>
               <arg evaluator="xml" expression="get-property('birth_date')"/>
               <arg evaluator="xml" expression="get-property('sex')"/>
               <arg evaluator="xml" expression="get-property('street_line1')"/>
               <arg evaluator="xml" expression="get-property('city')"/>
               <arg evaluator="xml" expression="get-property('stat_code')"/>
               <arg evaluator="xml" expression="get-property('zip')"/>
            </args>
         </payloadFactory>

在执行上述有效负载工厂介体时，我收到以下错误。

可能是什么原因？我哪里错了？

请帮助克服这种情况。

您通过$ 1，$ 2等插入的参数 - 是字符串还是数字？如果字符串 - 将它们放入＆＃34;＆＃34;，如：

"UserName":"$2",
"StudentID":$3,
"FirstName":"$4",
