Hi team

I'm using the below code for downloading files from the SFTP server.

` DataLakeFileSystemClient fileSystemClient = new DataLakeFileSystemClient(connectionString, "container");

        DataLakeDirectoryClient processDirectory = fileSystemClient.GetDirectoryClient("testProcessDir");


        using (var sftp = new SftpClient(host, username, password))
        {
            sftp.Connect();
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {
                string remoteFileName = file.Name;
                if (!file.Name.StartsWith(".") && (DateTime.UtcNow - file.LastWriteTimeUtc).TotalHours < 1)
                {
                    DataLakeFileClient newfile = processDirectory.CreateFile(file.Name);

                    using (Stream stream = newfile.OpenWrite(overwrite: true))
                    {


                        sftp.DownloadFile(remoteDirectory + remoteFileName, stream);
                    }
                }
            }`

After downloading 1 or few files it gives execption as $exception {"Failure"} Renci.SshNet.Common.SshException

Please suggest something with which I could download all the files.

Thanks,

Unfortunately the actual call stack is lost in this case and I have labelled this issue as Bug because of that.
However in this case the error is sent by the server and more information should be available in the server logs.
