CopyObjectRequest wrong host URL

[FaZeRs]

Describe the bug

When I try to copy object from one folder to another in same bucket I get an error Invalid response status from request (aws-c-s3: AWS_ERROR_S3_INVALID_RESPONSE_STATUS). This happens only for CopyObject, for HeadObject, ListObjects, GetObject, PutObject everything is correct

Expected Behavior

Expected host URL should be s3.giraffe360-mimosa.com and file should be copied
from
/cold-data/projects/db9768d14f7c4055aa7518e42b633888/floorplan/roomsketcher/floorplan-ALL-final_1_0.svg
to
/cold-data/projects/db9768d14f7c4055aa7518e42b633888/floorplan/roomsketcher/final_backups/floorplan-ALL-final_1_0_2024-01-24_13-03-01.svg

Current Behavior

Based on logs I see it has wrong host URL

For other requests it is correct

Reproduction Steps

Aws::Auth::AWSCredentials credentials(access_key, secret_key, session_token);

Aws::S3Crt::ClientConfiguration config;
config.endpointOverride = host_;
config.useVirtualAddressing = false;
config.verifySSL = false;
config.enableEndpointDiscovery = false;
config.enableHostPrefixInjection = false;
config.region = Aws::Region::US_EAST_1;
config.scheme = Aws::Http::Scheme::HTTPS;
config.disableMultiRegionAccessPoints = true;
config.disableS3ExpressAuth = true;
config.payloadSigningPolicy = Aws::Client::AWSAuthV4Signer::PayloadSigningPolicy::Never;

config.enableEndpointDiscovery = false;
config.enableHostPrefixInjection = false;
config.version = Aws::Http::Version::HTTP_VERSION_3;

std::unique_ptr<Aws::S3Crt::S3CrtClient> client = std::make_unique<Aws::S3Crt::S3CrtClient>(credentials, config);

Aws::S3Crt::Model::CopyObjectRequest request;
request.SetBucket(bucket);
request.SetKey(dst_path);
request.SetCopySource(bucket + "/" + src_path);
auto outcome = client->CopyObject(request);

I can repro this with the sample code you gave. Looking into what might be causing this.

This is a problem with aws-c-s3. Opening an issue on that repo to be tracked there: awslabs/aws-c-s3#424. Leaving this issue open for now, I will make sure to update here when that one gets closed

The CRT client has a very limited support for copy object. One of the limitation is it only supports virtual host addressing style, here

In your case, you override the host to s3.giraffe360-mimosa.com, which is not the virtual hosting for S3 bucket. So, it's not currently supported by CRT client and currently we don't have any plan to support it. You can create a feature request.

I'd recommend to use the regular C++ S3 client for copy object instead of CRT, since there won't be much benefits to use CRT to do copy object (No throughput improvement), since the work mostly done in the server side.
