当发布Blazor WASM项目时，Net7 JWT Null引用?

Question

所以我一直在Net7预览版中工作，并一直试图部署一个具有身份和身份验证的WASM项目，该项目在本地工作良好。当我部署网站500并挖掘一些日志时，我得到:

2022-11-07T13:42:28.854805951Z fail: Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerHandler[3]
2022-11-07T13:42:28.854856853Z       Exception occurred while processing message.
2022-11-07T13:42:28.854865053Z       System.NullReferenceException: Object reference not set to an instance of an object.
2022-11-07T13:42:28.856255318Z          at Microsoft.AspNetCore.ApiAuthorization.IdentityServer.IdentityServerJwtBearerOptionsConfiguration.ResolveAuthorityAndKeysAsync(MessageReceivedContext messageReceivedContext)
2022-11-07T13:42:28.856286120Z          at Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerHandler.HandleAuthenticateAsync()

在我的Program.cs中有

builder.Services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(connectionString));
builder.Services.AddDatabaseDeveloperPageExceptionFilter();
builder.Services.AddDefaultIdentity<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddEntityFrameworkStores<ApplicationDbContext>();
builder.Services.AddIdentityServer()
    .AddApiAuthorization<ApplicationUser, ApplicationDbContext>();
builder.Services.AddAuthentication()
    .AddIdentityServerJwt()
    .AddJwtBearer()
    .AddGoogle(googleOptions =>
    {
        googleOptions.ClientId = builder.Configuration["Authentication:Google:ClientId"];
        googleOptions.ClientSecret = builder.Configuration["Authentication:Google:ClientSecret"];
    });
builder.Services.AddControllersWithViews();
builder.Services.AddRazorPages();
builder.Services.AddHttpContextAccessor();
var app = builder.Build();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseMigrationsEndPoint();
    app.UseWebAssemblyDebugging();
}
else
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}
app.UseHttpsRedirection();
app.UseBlazorFrameworkFiles();
app.UseStaticFiles();
app.UseRouting();
app.UseIdentityServer();
app.UseAuthentication();
app.UseAuthorization();

app.MapRazorPages();
app.MapControllers();
app.MapFallbackToFile("index.html");
app.Run();

我一直试图遵循不同的Duende指南，但即使当我最终得到它在本地运行，我仍然得到相同的错误。我试过删除AddAuthentication()中的JWT行，这似乎也没有帮助。

你需要在appsettings.json

"IdentityServer": {
"Key": {
  "Type": "Development"
}   },

修改为正确的类型
