Blazor Server-Side (or Hybrid)—Empty Results

[IEvangelist]

Edge returns 325 voices on my machine. This is way more than I think any of us were expecting. With that said, since the Blazor Server-side approach relies on ASP.NET Core SignalR, you must configure an appropriate message buffer size to handle this. Otherwise, the calls to ISpeechSynthesisService.GetVoiceAsync will not work. It results in the following error:

Error: Connection disconnected with error 'Error: Server returned an error on close: Connection closed with an error.'

If you have detailed errors on, you might instead see an error like this:

Error: The maximum message size of 32768B was exceeded.

Work around

In the Program file:

builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents(options => options.DetailedErrors = true)
    .AddHubOptions(options =>
    {
        options.EnableDetailedErrors = true;
        options.MaximumReceiveMessageSize = 102_400; // 100 KB or more
    });
