Hello,

[cloudshell-user@ip-10-x-x-x ~]$ aws iam delete-role --role-name AWSServiceRoleForApplicationAutoScaling_DynamoDBTable
An error occurred (UnmodifiableEntity) when calling the DeleteRole operation: Cannot perform the operation on the protected role 'AWSServiceRoleForApplicationAutoScaling_DynamoDBTable' - this role is only modifiable by AWS

IAM CONSOLE

Hello.

I would appreciate it if you could check the following part about the problem of deleting AWSServiceRoleForApplicationAutoScaling_DynamoDBTable IAMRole.

First, the error indicates that the dynamodb table exists. Please refer to the link below because you need to delete the dynamodb table to delete the corresponding IAM role.
- Delete table : https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/SQLtoNoSQL.DeleteData.html

Secondly, after deleting the dynamodb table, you will be able to delete the IAM role by referring to the contents below.
- Delete role : https://docs.aws.amazon.com/autoscaling/application/userguide/application-auto-scaling-service-linked-roles.html#delete-service-linked-role

Thank you.

Hello,

Thank you for your response.
I had no dynamo table under the AWS console ,however under CLI one table was found when trying to delete the role.
{
    "Status": "FAILED",
    "Reason": {
        "Reason": "Service linked role is still in use",
        "RoleUsageList": [
            {
                "Region": "eu-central-1",
                "Resources": [
                    "table/testdb"
                ]
            }
        ]
    }
}

Trying to see what is all about under CLI this says table not found
$ aws dynamodb describe-table --table-name testdb
An error occurred (ResourceNotFoundException) when calling the DescribeTable operation: Requested resource not found: Table: testdb not found

Checked again under the region eu-central-1 maybe I've lost my mind and still no testdb table can be seen so the approach that I took was:
1.created a fresh table testdb in  eu-central-1
2.deleted the table testdbd in  eu-central-1
3.using CLI, success, was able to delete the role..
$ aws iam get-service-linked-role-deletion-status --deletion-task-id "task/aws-service-role/dynamodb.application-autoscaling.amazonaws.com/AWSServiceRoleForApplicationAutoScaling_DynamoDBTable/aad20187-1c46-4135-aabf-7a5020939a41"
{
    "Status": "SUCCEEDED"
I guess it was some sort of ghost dbtest leftover somewhere,somehow  :)
Hope it helps someone with same issue.
Thank you for your help AWS-User-6847632 much appreciated
