Azure 中的 Blazor：组件记录列表无效

Question

将我们的 blazor 应用程序部署到 azure 时，它​​五分之四失败并出现此错误（从 chrome 开发工具复制）：

[2019-12-16T11:12:55.214Z] Information: Normalizing '_blazor' to 'https://example.com/_blazor'.
[2019-12-16T11:12:55.470Z] Information: WebSocket connected to wss://example-web-signalr-service.service.signalr.net/client/?hub=componenthub&asrs.op=%2F_blazor&negotiateVersion=1&asrs_request_id=...&id=...&access_token=...

我们无法理解这一点。blazor 像这样失败的原因可能是什么？为什么它不会在我们本地的开发人员机器上失败？在谷歌中很难找到任何关于此的信息。

请告诉我是否需要提供更多信息。我不确定哪些代码片段可能是有用的信息。

尝试这个：

services.AddSignalR().AddAzureSignalR(options =>
{
    options.ServerStickyMode = Microsoft.Azure.SignalR.ServerStickyMode.Required;
});
