When viewing an object through the AWS S3 console, under owner I see no value. Viewing the object owner attribute on a query of objects indicates the value of owner for these objects is None.
An example query that would return this information:
[o.owner for o in s3.Bucket(bkt_name).objects.filter(Prefix=filter_pattern)]
In the above case, I would see a list returning w/ None values, eg:
[None, None, ...]
These objects were uploaded with ACL set to bucket owner controlled:
My expectation would be that the bucket owner would show up here, not a None. What I'd like to understand is what would cause a None to appear. Is this a permissions issue in that I am not allowed to see the owner name? I presume all objects must have an owner and thus None is not an "actual" option but merely rendered if I am in fact no allowed to see the actual string.
