Bucket Owner displayName null even though it isn't

[anas-ben-ouaghrem]

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

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.

@anas-ben-ouaghrem is this still an issue? If it is, it can be easily checked with the verbose wirelogging.

Here's an example of the verbose wirelogs that shows the ListBuckets XML response with the DisplayName information:
