Ссылка на необъявленную сущность 'nbsp' исключение при создании папки в Shrepoint - C #

Question

Мы используем приведенный ниже код для создания папки в SharePoint, используя c #:

private static bool CreateFolder(ClientContext context, string newFolderLocation, string listName, string relativePath, string newFolderName)
        {
            bool folderCreated = false;
            try
            {
                Web web = context.Web;
                List list = web.Lists.GetByTitle(listName);

                ListItemCreationInformation newItem = new ListItemCreationInformation();
                newItem.UnderlyingObjectType = FileSystemObjectType.Folder;

                newItem.FolderUrl = newFolderLocation;
                if (!relativePath.Equals(string.Empty))
                {
                    newItem.FolderUrl += relativePath + "/";
                }

                LogHelper.LogInfo(newItem.FolderUrl+","+ newFolderName);
                //Check if Folder exists in SharePoint.
                bool folderExists = CheckIfFolderExists(context, list, newItem.FolderUrl, newFolderName);

                //Create the folder in SharePoint if does not exist.
                if (!folderExists)
                {
                    LogHelper.LogInfo("folder exists:" + folderExists);
                    newItem.LeafName = newFolderName;
                    Microsoft.SharePoint.Client.ListItem item = list.AddItem(newItem);
                    item["Author"] = 9;
                    item["Editor"] = 9;
                    item.Update();
                    context.ExecuteQuery();
                }
                folderCreated = true;
            }
            catch (Exception ex)
            {
                LogHelper.ErrorLogging(ex);
            }
            return folderCreated;
        }

Используя этот код, мы пытаемся создать папку с именем "1122-test" в папке, например "https://test.sharepoint.com/sites/DevSandbox/test/Shared%20Documents/folderlocation/".

Код отлично работает на локальном компьютере, но дает следующие исключения только на производстве:

Мы делаем что-то не так или есть какая-то конфигурация, которую нам нужно сделать на рабочем сервере.
