Has anyone encountered such a problem???

Hi there,

I use the following code (CSOM) to upload documents. If I change the site url from "https://extlab.litwareinc.pri/" to"https://extlab.litwareinc.pri/sites/UAT" (It's a Site Collection under"https://extlab.litwareinc.pri/").no file can be uploaded and no any errors. so does anyone have any idea??

using (ClientContext clientContext = new ClientContext("https://extlab.litwareinc.pri/"))
                {
                    string pwd = "pass@word1";

                    SecureString passWord = new SecureString();
                    foreach (char c in pwd.ToCharArray()) passWord.AppendChar(c);

                    //clientContext.Credentials = new SharePointOnlineCredentials("administrator@litwareinc.pri", passWord);
                    clientContext.Credentials = new NetworkCredential("litwareinc\\Administrator", passWord);
                    clientContext.AuthenticationMode = ClientAuthenticationMode.Default;
                    string filepath = @"C:\Users\Administrator\Desktop\00.00 sharepoint case studies v2 (4 Malaysia).pptx";

                    /// Issue: Cannot invoke HTTP DAV request. There is a pending query.
                    if (clientContext.HasPendingRequest)
                        clientContext.ExecuteQuery();

                    using (FileStream fs = new FileStream(filepath, FileMode.Open))
                    {
                        Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, "/Shared Documents/" + System.IO.Path.GetFileName(filepath), fs, true);
                    }

                }
