为什么我的 C# 在 SharePoint 上找不到任何列表？

Question

我正在尝试在网站 url https://example.sharepoint.com/MySite

的 Online SharePoint 上创建一个文件夹

我真的不关心 SharePoint 列表，但我找不到任何关于 SharePoint API 的信息，它向消费者隐藏了这个实现细节，也找不到任何足够好地预测我的需求的文档告诉我需要做什么，所以我正在努力使用列表。

目前，我只想简单地列出我网站上存在的所有列表。我的网站有一些简约的内容，所以我希望世界上所有东西都有列表，应该有一些列表，我应该能够以某种方式列出它们。

我有以下代码：

            using (ClientContext context = _authenticationManager.GetContext())
            {
                Web web = context.Web;
                context.Load(web.Lists, lists => lists.Include(list => list.Title, list => list.Id));
                context.ExecuteQuery();

                foreach (List list in web.Lists)
                {
                    _logger.LogInformation(list.Title);
                }
            }

我已经能够使用调试器和控制台来确认 AuthenticationManager 已成功生成身份验证令牌。

当代码执行时，context.ExecuteQuery(); 导致以下错误：

我错过了什么 and/or 做错了什么？我该如何纠正？

感谢@arconaut 在评论中提出的问题：

似乎身份验证管理器只使用域，而不是完整的 URL 来进行身份验证。

虽然我的站点 URL 设置为 https://example.sharepoint.com/MySite, it should have been https://example.sharepoint.com/sites/MySite。

（我想我在尝试遵循一些可能与我的 Salesforce 版本不匹配的文档时从配置中删除了“站点”。）
