在Shrepoint中创建文件夹时引用未声明的实体'nbsp'异常-C＃

Question

我们正在使用以下代码使用c＃在SharePoint中创建文件夹：

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;
        }

使用此代码，我们试图在文件夹位置“ https://test.sharepoint.com/sites/DevSandbox/test/Shared%20Documents/folderlocation/”中创建一个名为“ 1122-test”的文件夹。

代码在本地计算机上工作正常，但仅在生产环境中会给出以下异常：

我们是在做错什么，还是在生产服务器中需要做任何配置？
