Not able to run the code with MRAP enabled

[karrisri]

Hi Team,

I'm trying to work with MRAP(Multi Region Access Point) enabled in s3 bucket from java sdk, in which the code working fine with the bucket name giving directly, but the same code not working WRT the MRAP enabled url.
bucket name : br-gtodev-amtdcr-sftp-us-east-1-s3 --> working
accessPointArn : arn:aws:s3::578294835321:accesspoint/m8dzbp9kydd5u.mrap -->notworking

java code used was as below.
S3Client s3Client = S3Client.builder()
.region(region) -->region given as "us-east-1"
.credentialsProvider(DefaultCredentialsProvider.create())
.build();

//to fetch the list of objects
ListObjectsV2Request listRequest = ListObjectsV2Request.builder().bucket(bucketName).prefix(keyName)
.build();

		**ListObjectsV2Response listing = s3Client.listObjectsV2(listRequest);** 
		List<S3Object> s3Objects = listing.contents();

if I pass bucket name its working fine but if I pass MRAP arn then getting the following issue at the line "ListObjectsV2Response listing = " as below.

ERROR: We encountered an internal error. Please try again. (Service: S3, Status Code: 500, Request ID: 44KBWEYZV5ER4ZPF, Extended Request ID: FAkkftsSX41Ts/UQeyKh7yERTgzCur+GINgVNq+/0bFxMf96fKGpS0wZLXeY7JkgE0jxPsynJNM=).

Can you please help me out on this and let me know the process to be followed for this to work.
