Summary

Attempting to publish a basic .NET Core React app with auth functionality I am receiving an error with IdentityServer. This is using dotnet new react --auth Individual, .Net Core 3.0 Preview5, and following the instructions here and here.

I've uploaded the PFX via the TLS/SSL settings. I've also ensured the certificate works on my dev environment, finding that GetMyX509Certificate returns the cert.

The code causing the issue seems to be in Configure in Startup.cs when running app.UseIdentityServer():

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        //...

        Log.Information("Configure - running app.Use: Authentication, IdentityServer");

       Log.Information("Configure - running app.Use: Authentication");
        app.UseAuthentication();
        Log.Information("Configure - running app.Use: IdentityServer");
        app.UseIdentityServer();

        //CODE DOESN'T MAKE IT HERE!!!
        Log.Information("Configure - running app.UseMvc");

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller}/{action=Index}/{id?}");
        });

        Log.Information("Configure - running app.UseSpa");

        app.UseSpa(spa =>
        {
            spa.Options.SourcePath = "ClientApp";

            if (env.IsDevelopment())
            {
                spa.UseReactDevelopmentServer(npmScript: "start");
            }
        });

        Log.Information("Configure - Done!");
    }

Things I've tried

There's not much out there in the way of solutions. The IdentityServer4 only talks about types in terms of Grant Types, but this seems prior to that.

As you already answered - The solution is to add the following settings into appsettings.json, within the "IdentityServer" brackets. This followed the "Clients" element:

For File

 "IdentityServer": {
    "Key": {
      "Type": "File",
      "FilePath": "C:\cert.pfx",
      "Password": "password123"
    }
  }

For Development (don't use in production obviously)

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

For Store

"IdentityServer": {
  "Key": {
    "Type": "Store",
    "StoreName": "My",
    "StoreLocation": "CurrentUser",
    "Name": "CN=MyApplication"
  }
}
