Amazon S3 translator currently is not working. I see two issues
1) The Amazon SDK jar that is being used is very old from 2016, this should be updated to latest either 1.11.695 or 2.0. I am guessing 2.0 will be more work that can be handled in a separate issue.
2) The default endpoints that are generated are wrong for S3, it looks like this has changed by Amazon. These need to be in the form "<bucket>.s3.amazonaws.com"
