Como definir a configuração de bloqueio de objetos em um bucket

O exemplo de put-object-lock-configuration a seguir define um bloqueio de objetos de 50 dias no bucket especificado.

aws s3api put-object-lock-configuration \
    --bucket my-bucket-with-object-lock \
    --object-lock-configuration '{ "ObjectLockEnabled": "Enabled", "Rule": { "DefaultRetention": { "Mode": "COMPLIANCE", "Days": 50 }}}'

Este comando não produz saída.
