S3-CRT Client signature error on s3 object keys with special characters

[eranh-bb]

Describe the bug

When moving from the regular s3 client to s3-crt client we've been getting the following errors on object keys that have special characters in them (i.e. '=' sign)
'The request signature we calculated does not match the signature you provided. Check your key and signing method.'

1. the issue is not present with the regular s3 client in the same sdk version
2. encoding the key produces a 'The specified key does not exist.' error (in trace logs I can see the query is done with double encoding of the key).

we are using sdk with tag version:

help would be greatly appreciated

Expected Behavior

s3-crt client would work seamlessly against the same object keys that the regular s3 client supports.

Current Behavior

s3-crt client fails on object keys with special characters with the following message:
The request signature we calculated does not match the signature you provided. Check your key and signing method.

Reproduction Steps

example code:

#include <aws/core/Aws.h>
#include <aws/core/client/ClientConfiguration.h>

#include <aws/s3-crt/model/GetObjectRequest.h>
#include <aws/s3-crt/S3CrtClient.h>

#include <aws/s3/S3Client.h>
#include <aws/s3/model/GetObjectRequest.h>

int main(int argc, char ** argv) {

    // Init AWS API
    Aws::SDKOptions awsSdkOptions;
    awsSdkOptions.loggingOptions.logLevel = Aws::Utils::Logging::LogLevel::Trace;
    awsSdkOptions.httpOptions.installSigPipeHandler = true;
    Aws::InitAPI(awsSdkOptions);

    std::string bucket("your_bucket");
    std::string objectKey("year=2024/file.json");
    std::string region("us-east-1");

    // s3 client code: --> works
    {
        Aws::Client::ClientConfiguration config;
        config.region = region;

        Aws::S3::S3Client s3Client(config);

        Aws::S3::Model::GetObjectRequest objectRequest;
        objectRequest.WithBucket(bucket.c_str()).WithKey(objectKey.c_str());

        auto getObjectOutcome = s3Client.GetObject(objectRequest);

        if (!getObjectOutcome.IsSuccess()) { 
            std::cerr << "failed s3 client get: " << getObjectOutcome.GetError().GetMessage() << std::endl;
        } else {
            std::cerr << "s3 client success!" << std::endl;
        }
    }

    // s3-crt client code --> fails on signature verification
    {
        Aws::S3Crt::ClientConfiguration config;
        config.region = region;

        Aws::S3Crt::S3CrtClient s3Client(config);

        Aws::S3Crt::Model::GetObjectRequest objectRequest;
        objectRequest.WithBucket(bucket.c_str()).WithKey(objectKey.c_str());

        auto getObjectOutcome = s3Client.GetObject(objectRequest);

        if (!getObjectOutcome.IsSuccess()) {
            std::cerr << "failed s3 CRT client get: " << getObjectOutcome.GetError().GetMessage() << std::endl;
        } else {
            std::cerr << "s3 CRT client success!" << std::endl;
        }
    }

    Aws::ShutdownAPI(awsSdkOptions);
}
