Could not parse XML response when getObjectAttributes

[evil0th]

Describe the bug

I have several two S3 buckets where data is written to the buckets . when I run into an issue where get the object attributes causes an exceptIon:

The block of code that causes this is as follows:

 client.getObjectAttributes(GetObjectAttributesRequest.builder()
			.bucket(bucket)
			.key(key)
			.objectAttributes(ObjectAttributes.E_TAG)
			.build());

Expected Behavior

retun object ETag attribute

I've also run into this issue. It seems as though MinIO hasn't implemented the get-object-attributes functionality yet (this is also mentioned here) . Rather use HeadObjectRequest to retrieve the e-tag.
