创建混合连接Azure Rest API

Question

我正在尝试使用rest API在Azure BizTalk服务中创建混合连接。不过，我收到了这个错误：

<Error xmlns="http://schemas.microsoft.com/windowsazure" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
  <Code>InternalError</Code>
  <Message>The server encountered an internal error. Please retry the request.</Message>
</Error>

请求：
