No ability to create 0 byte folder in S3

[kevinleadoutlabs]

Describe the bug

Trying to create a zero byte folder in S3 (as you can do in the console) but the trailing "/" always gets striped.

Steps To Reproduce

let folderPath = "test/"
let path = StringStoragePath.fromString(folderPath)
print("path: \(path.resolve(""))")
let options = StorageUploadDataRequest.Options(
    contentType: "application/x-directory"
)
let folderTask = Amplify.Storage.uploadData(
    path:path,
    data:Data(),
    options:options
)
_ = try await folderTask.value
logger.verbose("path created: \(result)")

Expected behavior

create a zero byte folder (trailing back slash)

both print statements reference that "test/" was created.

Is this a regression?

No

Regression additional context

this worked fine in the old SDK when I was using: guard let putObjectRequest = AWSS3PutObjectRequest() else {
throw NSError(domain: "AWSS3Error", code: -1, userInfo: [NSLocalizedDescriptionKey: "Failed to create PutObjectRequest"])
}
putObjectRequest.bucket = bucket
putObjectRequest.key = finalFolderPath
putObjectRequest.body = "".data(using: .utf8)

    if debug{
        logger.debug("attempting creation of: \(pathDisplay)")
    }
    
    try await s3.putObject(putObjectRequest)

I have created a bug in aws-sdk-swift repository to see if this is a correct behavior.

As a workaround, I experimented with by adding an extra forward slash and it resulted in creation of a folder. Please try it out and let us know if this works for you.

let folderPath = "public/test//"
let path = StringStoragePath.fromString(folderPath)
print("path: \(path.resolve(""))")
let options = StorageUploadDataRequest.Options(
    contentType: "application/x-directory"
)
let folderTask = Amplify.Storage.uploadData(
    path:path,
    data:"".data(using: .utf8)!,
    options:options
)

do {
    let result = try await folderTask.value
    print("Path created: \(result)")
} catch {
    print("Upload failed with error: \(error)")
}
