Aws 机密管理器

Question

I tried writing a hostedlambdarotation property in AWS cloudformation to rotate my credentials after every X days, but the deployment fails stating the following error - "Transform AWS::SecretsManager-2020-07-23 failed with: PostgreSQLSingleUser is not a supported rotation engine type."

Here in the documentation it says that the above mentioned rotation type is supported. Hostedlambdarotation property

Has anyone faced a similar issue? I am using a postgresql thus want to use the above mentioned rotation policy.

Any help will be much appreciated!

Edit: Sample Code

   {
  "Transform": "AWS::SecretsManager-2020-07-23",
  "Resources": {
    "Test": {
      "Type": "AWS::SecretsManager::Secret",
      "Properties": {
        "Name": "Test",
        "Description": "Secrets for db connectivity",
        "SecretString": "{\"username\":\"test\",\"password\":\"test\",\"engine\":\"postgres\",\"host\":\"test.rds.amazonaws.com\",\"port\":\"5432\",\"dbname\":\"test\"}"
      }
    },
    "TestAttachment": {
      "Type": "AWS::SecretsManager::SecretTargetAttachment",
      "Properties": {
        "SecretId": {
          "Ref": "Test"
        },
        "TargetId": "arn:aws:rds:test",
        "TargetType": "AWS::RDS::DBInstance"
      }
    },
    "TestSecretRotationSchedule": {
      "Type": "AWS::SecretsManager::RotationSchedule",
      "Properties": {
        "SecretId": {
          "Ref": "Test"
        },
        "HostedRotationLambda": {
          "RotationType": "PostgreSQLSingleUser",
          "RotationLambdaName": "SecretsManagerRotation",
          "VpcSecurityGroupIds": "sg-testid",
          "VpcSubnetIds": {
            "Fn::Join": [
              ",",
              [
                "subnet-test01",
                "subnet-test02"
              ]
            ]
          }
        },
        "RotationRules": {
          "AutomaticallyAfterDays": 45
        }
      }
    }
  }
}

Maybe it has been updated since you last tried? I just used more or less than same syntax in yaml and it just deployed successfully in CFN.

    AuroraSecretRotationSchedule:
      Type: AWS::SecretsManager::RotationSchedule
      DependsOn:
        - SecretAuroraClusterAttachment
        - AuroraDBInstance
      Properties:
        HostedRotationLambda:
          RotationType: PostgreSQLSingleUser
          RotationLambdaName: "PGMasterSecretRotationLambda"
        SecretId: !Ref AuroraMasterSecret
        RotationRules:
          AutomaticallyAfterDays: 30

Funny thing is I would never have gotten it if not for your question-- I specified the MasterSecretArn parameter previously, which caused an error. Disclaimer: I haven't tested if this lambda actually works, just that it deployed w/o error.
