While I was trying to setup the S3 Sink connector and tightening as much as possible the permissions on the S3 bucket and the prefix I wanted the connector to use, I came to realize that there is a non documented (at least I cannot find it [here](https://docs.lenses.io/5.5/connectors/sinks/s3sinkconnector/)) need for a prefix named `.indexes` at the root of the bucket. Without that, the connector will just not work in my case. Just wanted to open the discussion here about that prefix, thanks! ---
