Azure中的Blazor :组件记录列表无效

Question

将blazor应用程序部署到azure时，五分之四的情况下都会失败，并出现以下错误(从chrome dev工具中复制)：

[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=...
[2019-12-16T11:12:55.548Z] Error: The list of component records is not valid.

我们无法从这件事中找到任何意义。什么可能是导致blazor失败的原因？为什么它不会在我们本地的开发者机器上失败呢？在谷歌中很难找到关于这方面的任何东西。

如果我需要提供更多信息，请告诉我。我不确定哪些代码片段可能是有用的信息。

试试这个：

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