Hello,
the object created by https://github.com/aws-solutions-library-samples/cloud-intelligence-dashboards-data-collection/blob/main/data-exports/deploy/data-exports-aggregation.yaml#L1369 will currently just fail the replication, if there are multiple aggregation buckets syncing into the same shared bucket.
This currently causes an open AWS Health Event "S3 planned lifecycle event" for the bucket, since objects with failed replication get their lifecycle events paused.
Maybe exclude the Object from the replication rule ?
Best Regards
Robin
