Bucket Owner displayName null even though it isn't

[anas-ben-ouaghrem]

Describe the bug

Hello,
I was retrieving the owner display names for all of my s3 buckets a week ago then today and with the same code the display name became null. I checked in the cli and I retrieve the expected display name, meaning that it shouldn't be null

Expected Behavior

The actual display name gets retrieved

Current Behavior

The display name is always null

Reproduction Steps

List buckets = s3Client.listBuckets();
for ( Bucket bucket : buckets) {
System.out.println(bucket.getOwner().getDisplayName());
}

Possible Solution

Hello @Anas-Ben-Oughrem,

Can you please check and confirm the AWS region it's pulling via AWS SDK for Java?

DisplayName is supported only in certain AWS regions, as specified here.

If you still have further questions, can you kindly enable verbose wire logging and provide us the logs? Kindly redact any sensitive information the log may contain.

Instructions to enable wire logging can be found here.

Regards,
Chaitanya
