unable to create vertical scaling stack using ops-automator.template

Due to the new changes in April, the newly created S3 buckets have S3 Block Public Access enable and S3 access control lists (ACLs) disable automatically. So if you want to enable ACLs for a bucket, you can set the ObjectOwnership parameter to ObjectWriter. The ops-automator template is creating one of the S3 bucket through S3LoggingBucket resource which has AccessControl set to LogDeliveryWrite, therefore according to the new policy for enabling ACLs, you have to add ObjectOwnership: ObjectWriter, otherwise you will encounter the below error :

Bucket cannot have ACLs set with ObjectOwnership's BucketOwnerEnforced setting (Service: Amazon S3; Status Code: 400; Error Code: InvalidBucketAclWithObjectOwnership; Request ID

In ops-automator template, you can edit the template and add ObjectOwnership to ObjectWriter, which looks like below :

  S3LoggingBucket:
    DeletionPolicy: Retain
    Type: 'AWS::S3::Bucket'
    Properties:
      BucketName: !Sub 'aws-opsautomator-s3-access-logs-${AWS::AccountId}-${AWS::Region}'
      AccessControl: LogDeliveryWrite
      OwnershipControls:                 ### Add ObjectOwnership to ObjectWriter
        Rules:
          - ObjectOwnership: ObjectWriter
      VersioningConfiguration:
        Status: Enabled
      BucketEncryption:
        ServerSideEncryptionConfiguration:
          - ServerSideEncryptionByDefault:
              SSEAlgorithm: AES256
      Tags:

          Value: AWS Ops Automator Access Logs
