Java 400更新DueDate或使用DueDate创建新任务时请求错误

我正在尝试更新任务的dueDate:

Task updatedTask = service.tasks.get(gTask.getTaskListGuid(), gTask.getGuid()).execute();
updatedTask.setTitle(gTask.getTitle());
updatedTask.setNotes(gTask.getDescription());
updatedTask.setDue(gTask.getDueDate());
service.tasks.update(gTask.getTaskListGuid(), gTask.getGuid(), updatedTask).execute();

但api返回给我：

10:49:40,323 ERROR GTasksServiceProcessor.[main]processUpdatedTasks:81 - Can't update task: com.google.api.client.http.HttpResponseException: 400 Bad Request

哪里有问题？ 我在尝试使用dueDate创建新任务时也有相同的异常

我还发现了线程： 但这对我没有帮助。
