Hi,

I am using below payload for PutBucketLogging api and getting MalformedXML error in response. I have checked it with real AWS and it is working perfectly fine. Am I missing something or this needs a fix in localstack?

`"LoggingEnabled": {
            "TargetBucket": "test_bucket_name",
            "TargetPrefix": "log",
            "TargetGrants": [
                {
                    "Grantee": {
                        "URI": "http://acs.amazonaws.com/groups/s3/LogDelivery",
                        "Type": "Group",
                    },
                    "Permission": "WRITE",
                },
                {
                    "Grantee": {
                        "URI": "http://acs.amazonaws.com/groups/s3/LogDelivery",
                        "Type": "Group",
                    },
                    "Permission": "READ_ACP",
                },
            ],
        }
