找不到要执行的交易功能

Question

升级到作曲家v20后，我无法进行这种处理。

这是我的CTO模型-

`transaction Saldo extends Transaction {
--> Cliente cliente
--> Recargador recargador
o Double acreditarSalso
o Double debitarSaldo
}`

这是ionic-app上的模型

`export class Saldo extends Transaction {
  cliente: Cliente;
  recargador: Recargador;
  acreditarSaldo: number;
  debitarSaldo: number;
 }`

这是交易代码

`addSaldo (form: any): Promise<any> {
 this.Transaction = {
  $class: "org.abalazo.red.Saldo",
  "cliente": this.clienteCedula,
  "recargador": this.recargadorCedula,
  "acreditarSaldo": this.acreditar,
  "debitarSaldo": this.debitar,
   };
return this.transBalanceService.transaccionSaldo(this.Transaction)
.toPromise()
.then((result) => {
this.errorMessage = null;
this.transactionId = result.transactionId;
})
.catch((error) => {
if (error == 'Server error') {
this.errorMessage = "Could not connect to REST server. Please check your configuration details";
}else{
this.errorMessage = error;
}
});
}`

它抛出此错误。请告知我我做错了什么：

transaction returned with failure: Error: Could not find any functions to execute for transaction org.abalazo.red.Saldo#5593c9c21299297d4aa8e85b800a7ca1b818807171f7f4b22aeae9d8f6803c28"
