我正在尝试使用Deployment Manager SDK for Java编写一个应用程序来管理GCP部署。我能够成功列出部署，但无法更新部署，因为SDK抛出了如下所示的异常。
com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found

我的呼叫代码是：
val content = new Deployment().setTarget(target)
val updateResult = client.deployments().update(project, name, content)
.setCreatePolicy("CREATE_OR_ACQUIRE")
.setDeletePolicy("DELETE")
.setPreview(false)
.execute()
当我打开SDK的调试时，我看到以下交换：

所以它看起来像是一个无效的URL或对象。
但是，如果我使用gcloud CLI工具对--log-http做同样的事情，我会发现它正在达到完全相同的端点，但没有得到404:
==== request start ====
uri: https://www.googleapis.com/deploymentmanager/v2/projects/--redacted-project--/global/deployments/--redacted-deployment--?alt=json&preview=False&createPolicy=CREATE_OR_ACQUIRE&deletePolicy=DELETE
method: PUT
不知道从这里去哪里。
经过进一步挖掘，我注意到PUT请求中的主体JSON中的字段有所不同。gcloudCLI发送fingerprint、name和target，而Java SDK仅发送target。
隐藏在请求主体的文档中，它说您需要为update和其他一些方法设置fingerprint。
我修改了代码以首先获取部署，并在请求中包含fingerprint，它就开始工作了。
val content = new Deployment().setName(name).setFingerprint(fingerprint).setTarget(target)
val updateResult = client.deployments().update(project, name, content)
.setCreatePolicy("CREATE_OR_ACQUIRE")
.setDeletePolicy("DELETE")
.setPreview(false)
.execute()
在我看来，404是错误的。Google应该返回一个400，因为客户端在请求中没有包含必需的字段。
此外，SDK会进行大量的前置条件检查来捕获无效请求，但不包括此请求。我已经向谷歌提出了一个问题。
