Unable to create S3client without region in S3 V2 sdk

[rmunna]

The S3Client is failing with the following error when the client is created without the region specified. But where as in S3 sdk V1 it was possible to create the client without region.

Exception in thread "main" software.amazon.awssdk.core.exception.SdkClientException: Unable to load region from any of the providers in the chain software.amazon.awssdk.regions.providers.DefaultAwsRegionProviderChain@2e1d27ba: [software.amazon.awssdk.regions.providers.SystemSettingsRegionProvider@7bb58ca3: Unable to load region from system settings.

Providing region to the the S3Client builder resolves the above error but we get the authorization header malformed error when we perform an operation on the bucket of different region.

Exception in thread "main" software.amazon.awssdk.services.s3.model.S3Exception: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'us-east-2' (Service: S3, Status Code: 400, Request ID: DE3E42A889709617, Extended Request ID: Zw3FvxfFC2ap3+c69b1yJ6zCxdUVffO+gfBYXr5R3wHZKwnENH8soPo7jjLDped718OZkHOA8EY=)

v1

        AmazonS3 s3 = AmazonS3ClientBuilder.standard()
            .withCredentials(new AWSStaticCredentialsProvider(credentials))
            .withEndpointConfiguration(new EndpointConfiguration("https://s3.amazonaws.com",null))
            .build();

v2

S3Client.builder().credentialsProvider(StaticCredentialsProvider.create(credentials))
        .endpointOverride(URI.create("https://s3.amazonaws.com")).httpClient(sdkHttpClient)
        .build();

I am looking for a solution to create the S3Client without region as the customer doesn't provide the bucket region to us.
