AWS S3 Replication boto3 Python

I'm following best practices but Can someone help me understand Quick question that's been bugging me - I'm facing an issue with cross-region replication of S3 buckets... I've set up replication from my source bucket in us-east-1 to a destination bucket in eu-west-1. However, it seems that new objects uploaded to the source bucket are not being replicated to the destination bucket. I've checked to ensure that versioning is enabled on both buckets and that the replication configuration is in place, but I still see no replicated objects. Here’s the replication configuration I applied: ```json { "Role": "arn:aws:iam::123456789012:role/MyS3ReplicationRole", "Rules": [ { "Status": "Enabled", "Prefix": "", "Destination": { "Bucket": "arn:aws:s3:::my-destination-bucket", "StorageClass": "STANDARD" } } ] } ``` I also verified the IAM role permissions, and it looks like this: ```json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "s3:ReplicateObject", "s3:ReplicateDelete" ], "Resource": [ "arn:aws:s3:::my-source-bucket/*", "arn:aws:s3:::my-destination-bucket/*" ] } ] } ``` To troubleshoot, I checked the S3 replication metrics and found that there are no errors listed. However, it seems like the replication is simply not happening. I’ve also tried uploading new objects with different prefixes and checked the S3 console for any indications of issues, but everything appears normal. Has anyone faced similar issues or have any troubleshooting steps to check? I'm using the AWS SDK for Python (boto3) to manage my S3 operations, and the SDK version is 1.18.0. My development environment is Windows. Any help would be greatly appreciated! My development environment is macOS. Thanks in advance! I'm developing on Ubuntu 20.04 with Python. Any examples would be super helpful. The project is a microservice built with Python. Has anyone else encountered this?
