Malformed XML Error when calling put_bucket_replication boto3 API call from Lambda python

[yaminir]

When I call put_bucket_replication boto3 API call from my Lambda written in python code I see the below error: botocore.exceptions.ClientError: An error occurred (MalformedXML) when calling the PutBucketReplication operation: The XML you provided was not well-formed or did not validate against our published schema. Here is my function: response_bucket_replication_rule= s3client.put_bucket_replication(
Bucket=source,
ReplicationConfiguration={
'Role': role_arn,
'Rules': [
{
'Priority': 1,
'Prefix': "",
'Status': 'Enabled',
'SourceSelectionCriteria': {
'ReplicaModifications': {
'Status': 'Enabled'
}
},
'ExistingObjectReplication': {
'Status': 'Enabled'
},
'Destination': {
'Bucket': "bucketname",
# 'StorageClass': 'STANDARD',
},
# 'DeleteMarkerReplication': {
# 'Status': 'Enabled'
# }
},
]
},

Hi @yaminir thanks for reaching out. This is a server-side error from s3 that has been reported a few times, for example here and here. You could try referring to those or similar issues for suggestions. If you could provide your debug logs by adding boto3.set_stream_logger('') to your script (with sensitive info redacted) that could help give more insight into the behavior here.
