Try this:

public void Configure(IApplicationBuilder app,
    IHostingEnvironment env,
    ILoggerFactory loggerFactory)
{
    app.UseExceptionHandler("/Home/Error");
    app.UseStatusCodePagesWithRedirects("/Home/Error/{0}");

    app.UseMvc(routes =>
    {
        routes.MapRoute("default", "{controller=Home}/{action=Index}/{id?}");
        routes.MapWebApiRoute("defaultApi", "api/{controller}/{id?}");
    });

    app.Run(async context =>
    {
        context.Response.Redirect("/Home/Index");
        await Task.CompletedTask;
    });
}

app.Run() will catch all requests that doesn't match any of the routes defined earlier. This way you can get your custom spa fallback and use app.UseStatusCodePagesWithRedirects() at the same time.
