ComosDB中的Random MethodNotFoundExepection？ 知道我在做什么错吗？

Question

在过去的几天里，我曾看到此错误消息-尝试访问CosmosDB中托管的ASP.net Identity时-此代码在一年多来没有发生变化，我不知道为什么突然开始打ping。

这是我的启动类中的代码，用于初始化与DocumentDB和ASP.net Identity的连接（我正在使用完整的框架4.6.1（到年底升级到核心）-document.db客户端1.7.1（一直工作到前几天-冠军）

        services.AddSingleton<IDocumentClient>(InitializeDocumentClient(
         new Uri("https://recipesavants.documents.azure.com:443/"),
         "REDACTED"));
        // Add framework services.
        services.AddIdentity<DocumentDbIdentityUser, DocumentDbIdentityRole>()
            .AddDocumentDbStores(options =>
            {
                options.Database = "recipes";
                options.UserStoreDocumentCollection = "users";
            }).AddDefaultTokenProviders();

    private DocumentClient InitializeDocumentClient(Uri endpointUri, string authorizationKey)
    {
        // Create a DocumentClient and an initial collection (if it does not exist yet) for sample purposes
        DocumentClient client = new DocumentClient(endpointUri, authorizationKey, new ConnectionPolicy { EnableEndpointDiscovery = false });

        try
        {
            var db = client.ReadDatabaseAsync(UriFactory.CreateDatabaseUri("recipes")).Result;
        }
        catch (AggregateException ae)
        {
            throw ae;
        }

        try
        {
            // Does the Collection exist?
            var collection = client.ReadDocumentCollectionAsync(UriFactory.CreateDocumentCollectionUri("recipes", "users")).Result;
        }
        catch (AggregateException ae)
        {
            throw ae;
        }
        return client;
    }

这是堆栈跟踪-这是非常随机的-如果我杀死了浏览器，它似乎又可以工作了
