AWS SNS 主题子:Dead-letter 队列(重新驱动策略)权限被拒绝

AWS SNS Topic Sub: Dead-letter queue (redrive policy) permissions denied

我有一个 SNS 主题和订阅(实际上超过 1 个)设置以使用 SQS DLQ。但是每个人都告诉我我有政策错误。

我的 SNS 订阅设置了 DLQ:

我的队列存在:

我在 SQS 队列上设置了这个访问策略:

{
  "Version": "2008-10-17",
  "Id": "__default_policy_ID",
  "Statement": [
    {
      "Sid": "__owner_statement",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::1234:root"
      },
      "Action": "SQS:*",
      "Resource": "arn:aws:sqs:eu-west-2:1234:AggregateMonitoringDeadLetterQueue"
    },
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "sns.amazonaws.com"
      },
      "Action": "SQS:SendMessage",
      "Resource": "arn:aws:sqs:eu-west-2:1234:AggregateMonitoringDeadLetterQueue",
      "Condition": {
        "ArnLike": {
          "aws:SourceArn": [
            "arn:aws:sns:eu-west-2:1234:aggregator-state",
            "arn:aws:sns:eu-west-2:1234:rank-state-publication",
            "arn:aws:sns:eu-west-2:1234:rank-state-categorisation"
          ]
        }
      }
    }
  ]
}

我也试过在队列上有一个非常通用的访问策略:

{
  "Version": "2008-10-17",
  "Id": "__default_policy_ID",
  "Statement": [
    {
      "Sid": "__owner_statement",
      "Effect": "Allow",
      "Principal": {
        "AWS": "*"
      },
      "Action": "SQS:*",
      "Resource": "arn:aws:sqs:eu-west-2:1234:AggregateMonitoringDeadLetterQueue"
    },
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "sns.amazonaws.com"
      },
      "Action": "SQS:*",
      "Resource": "arn:aws:sqs:eu-west-2:1234:AggregateMonitoringDeadLetterQueue",
      "Condition": {
        "ArnLike": {
          "aws:SourceArn": "arn:aws:sns:eu-west-2:1234:*"
        }
      }
    }
  ]
}

我在关注这个:https://docs.aws.amazon.com/sns/latest/dg/sns-configure-dead-letter-queue.html(第 5 步解释了设置策略)

其他参考:https://docs.aws.amazon.com/sns/latest/dg/sns-dead-letter-queues.html

我一定是做错了什么,或者遗漏了什么?我无法摆脱错误。

请参阅 ,其中指出尽管有错误消息,失败的消息仍会正确发送到 DLQ。

在我这边,我可以确认我在我的 DLQ 中收到了那些失败的消息,它的配置与您的一样(通过遵循相同的文档 https://docs.aws.amazon.com/sns/latest/dg/sns-configure-dead-letter-queue.html)。
