AWS Rekognition FaceSearch - 没有作业完成通知

Question

有没有人成功完成面部搜索？

我在 2018 年 8 月 13 日东部时间上午 8 点左右使用 .Net API 提交了人脸搜索，但我的队列尚未收到工作完成的通知。来自 StartFaceSearch 的响应的 HttpStatusCode 是：OK

我有一个队列订阅了我请求接收通知的主题。我向主题发布了一条测试消息，队列确实接收了它。

这是代码...（已编辑标识符）

            // upload the video to Amazon
            IAmazonS3 client = new AmazonS3Client();
            // 1. Put object-specify only key name for the new object.
            var putRequest1 = new PutObjectRequest
            {
                BucketName = "mybucket.com",

问题是我指定的角色没有适当的权限来写入主题。我授予角色管理员访问权限，它开始工作了。
