S3 Delete Bucket Contents Extension fails to delete versioned buckets

[pbneamtu]

The AWS CloudFormation extension AwsCommunity-S3-DeleteBucketContents is not working as expected when trying to delete S3 buckets with versioning enabled. After reviewing the extension's code, it appears to have logic for handling versioned buckets, but the functionality isn't working in practice.

Current Behavior

• The extension successfully deletes contents of non-versioned buckets
• When attempting to delete a versioned bucket, the operation fails with the error:

  "The bucket you tried to delete is not empty. You must delete all versions in the bucket."
  

Investigation Done

• I've reviewed the extension's code which appears to include logic for handling bucket versions
• The IAM role includes the necessary s3:ListBucketVersions permission
• Despite this, the versioned bucket deletion is not working as expected

Expected Behavior

The extension should be able to delete all contents, including all versions of objects, from an S3 bucket before deletion.

Configuration Used

"s3deletebucketextenion": {
  "Type": "AWS::CloudFormation::TypeActivation",
  "Properties": {
    "Type": "RESOURCE",
    "PublicTypeArn": {
      "Fn::Sub": "arn:aws:cloudformation:${AWS::Region}::type/resource/c830e97710da0c9954d80ba8df021e5439e7134b/AwsCommunity-S3-DeleteBucketContents"
    },
    "ExecutionRoleArn": "${RoleArn}",
    "AutoUpdate": true
  }
}

IAM Permissions

The extension is configured with the following permissions:

{
  "Effect": "Allow",
  "Action": [
    "s3:DeleteObject",
    "s3:GetBucketTagging",
    "s3:ListBucket",
    "s3:ListBucketVersions",
    "s3:PutBucketTagging",
    "cloudformation:ListExports"
  ],
  "Resource": "*"
}

Questions

1. Is this a known limitation of the extension?
2. Could this be a version mismatch issue between the code and the deployed extension?
3. Are there any additional configurations needed to enable version deletion?
4. Are additional permissions required that aren't documented?

Environment

• Latest version of the AWS CloudFormation extension
