Json IBM集成总线：SOAP请求收到HTTP错误状态代码'；500'；

我是Ibm集成总线新手，一直在努力将数据从http节点转换为SOAP节点。

问题是，当我使用SOAP输入时，它可以工作，但当我使用Http输入更改它并将数据从JSON转换为XML时，错误会不断出现

计算节点代码：

     DECLARE reftoOut REFERENCE To OutputRoot.XMLNSC.ns2:MessageExtraitRequest;
     DECLARE reftoIn REFERENCE To InputRoot.JSON.Data;
        
        
        SET reftoOut.ns2:No_du_compte = reftoIn.No_du_compte;
        SET reftoOut.ns2:Date_operation = reftoIn.Date_operation;
        SET reftoOut.ns2:REFERENCE = reftoIn.REFERENCE;
        SET reftoOut.ns2:Libelle = reftoIn.Libelle;
        SET reftoOut.ns2:Date_valeur = reftoIn.Date_valeur;
        SET reftoOut.ns2:DEBIT = reftoIn.DEBIT;
        SET reftoOut.ns2:CREDIT = reftoIn.CREDIT;

我的WSDL（它与SOAPInput和postman配合得很好）

错误：
