It seems quite difficult...

Hint 2
Try to understand what this command do:

# aws --profile s3game s3api select-object-content --bucket <BUCKET> --key <OBJECT> --expression "SELECT s.Answer FROM s3object s WHERE Category = 'TREASURE'" --expression-type 'SQL' --input-serialization '{"CSV": {"FileHeaderInfo": "USE", "FieldDelimiter": ";"}, "CompressionType": "GZIP"}' --output-serialization '{"CSV": {}}' "treasure6"

No hints anymore. :) Get the secret code, and go to
