Question

上下文

我有一个包含三个实体的简单研讨会应用程序 - Job，Employee和Customer。我正在尝试创建Web界面，在这种情况下将添加新的Job。 Job与Employee和Customer有很多关系。在Job实体中，还有Employee和Customer的列表。

问题

当我尝试使用新的Job通过HTTP发布我的请求时，我收到错误的请求400，其中包含说明：

由于某些原因，服务器无法或不会处理请求被认为是客户端错误（例如，格式错误的请求）语法，无效请求消息框架或欺骗性请求路由）。

我不知道bug究竟在哪里。

添加Customer和Employee的表单可以正常使用。
