Ensure that you have set up the routing correctly in your Startup.cs file. It should map the URL path "account/createrole/" to the CreateRole action in your controller.

// Startup.cs

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "default",
        pattern: "{controller=Home}/{action=Index}/{id?}");
});

Make sure that the controller where this action correctly decorated with the [Controller] attribute.
