This is a question about the API that allows you to download files from Aspera Connect and confirm the completion of the file transfer.

When downloading a file from Aspera Connect, please let me know if an API function can confirm that the file has been downloaded and completed.

var transferCookie = {
idx : idx,
issueId : issueId,
};
var connectSpec = {
allow_dialogs: false,
use_absolute_destination_path: true
};
var transferSpec = {
paths: [
{
source: filePath,
destination: fileName
}
],
destination_root: targetDirectory,
remote_host: "${asperaVo.serverIp}",
remote_user: "${asperaVo.userId}"
remote_password: "${asperaVo.userPw}",
direction: 'receive',
authentication : 'password',
cipher : 'none',
overwrite_policy : 'always',
cookie: transferCookie,
fasp_port : "${asperaVo.faspPort}",
ssh_port : "${asperaVo.sshPort}",
title: fileName
};

asperaWeb.startTransfer(transferSpec, connectSpec,
{
success : function (data){
data.transfer_specs.forEach(function (transfer) {
fileDownInfo[idx].uuid = transfer.uuid;
fileDownInfo[idx].downloadFlag = true;
});
},
error : function (e){
}
});
}

If the Aspera client already has a file to download, it seems that Aspera HSTS skips it without actually downloading it, because the overwrite_policy of the transferSpec code above is always.

But Aspera Connect's log (aspera-scp-transfer.0) will record "status=success" for the file being downloaded.
Do you think the following API would be helpful to confirm that the file transfer has been completed, as in this case?
