RestSharp: Added files not being recieved

Expected Behavior

Send file to specified URL for storage

Actual Behavior

RestRequest.Files.Add(…) states the file has been added, but when RestClient.Execute(RestRquest) goes, I get a response “No files received”. This worked on the previous version. No code has changed from either my platform or the WebAPI it’s communicating with. What has changed that might be causing this?

Steps to Reproduce the Problem

    `private bool uploadPDF(SpoolDataRow pRow)
    {
        RestClient pClient = new RestClient(m_pLoginMgr.Server);
        pClient.Authenticator = new HttpBasicAuthenticator(m_pLoginMgr.Username, m_pLoginMgr.Password);
        RestRequest pPDFRequest = new RestRequest(Config.API_PUT_SPOOL_PDF(pRow.ID), Method.POST);
        pPDFRequest.AddHeader("Content-Type", "application/x-www-form-urlencoded");
        byte[] arBytes = File.ReadAllBytes(pRow.PDF);
        if (arBytes == null) return false;

        pPDFRequest.Files.Add(new FileParameter()
        {
            Name = "SpoolFile",
            Writer = pWriter =>
            {
                using (StreamReader pFile = new StreamReader(new MemoryStream(arBytes)))
                {
                    pFile.BaseStream.CopyTo(pWriter);
                }
            },
            FileName = Path.GetFileName(pRow.PDF),
            ContentLength = arBytes.Length,
            ContentType = "application/octet-stream"
        });

        IRestResponse pResponse = pClient.Execute(pPDFRequest);
        return pResponse.StatusCode == System.Net.HttpStatusCode.OK;
    }
