我们正在构建一个使用 Yodlee 数据的聚合应用程序，虽然与我们合作的大多数机构都有登录表单，其中包含一系列需要信息的字段，但有一个机构（节俭储蓄计划，内容服务 ID 4479）具有“ FieldInfoChoice”元素，它提供 2 个字段可供选择。在尝试测试和处理这个问题时，我们使用了 Java 示例应用程序“Aggregation12”（到目前为止，我们使用它作为所有其他 Yodlee SOAP 交互的实现示例，我们在这里找到了它）。
当尝试使用控制台应用程序“yconsole.sh”向用户添加“Thrift Savings Plan”帐户时，初始登录永远无法为我们提供输出，而是在生成登录信息提示之前出现错误。我们访问日志中的 XML 如下所示：

所以，2个问题：
1）这个错误的根源是什么？如果没有 java 示例应用程序如何使用这种类型的登录表单的示例，很难在我们的应用程序中正确处理它。
2) 您能否向我们提供一个在填写此表格时应发回的 XML 格式示例，因为我们可以合理地假设这与为我们已经成功工作的所有其他机构提交填写的字段不同和？
