New Post: SCP unexpected filename error

I'm adding SCP functionality to a PowerShell module I wrote, Downloading I have 0 problems from Unix and Linux hosts but uploading I'm getting a unexpected filename error. My code is bellow

try
{
    //Ceate instance of SCP Client with connection info
    var Client = new ScpClient(connectInfo);

    // Connect to  host using Connection info
    Client.Connect();
    WriteVerbose("Connection succesfull");
    var localfullPath = Path.GetFullPath(localfile);
    if (File.Exists(localfullPath))
    {
        WriteVerbose("Uploading "+localfullPath);
        FileInfo fil = new FileInfo(@localfullPath);
        Client.Upload(File.OpenRead(@localfullPath),remotefile);

        Client.Disconnect();
    }
}
catch (Exception ex)
{
    throw ex;
}

Here is an example of the error:

C:\Users\Carlos> Set-SCPFile -ComputerName 192.168.1.154 -Credential (Get-Credential) -LocalFile .\bashist.txt -Rem
oteFile /etc/ssh/sshd_config.bak -Verbose

Any idea why I could be getting this error?
