angular-cli: Could not resolve route

angular-cli: 1.0.0-beta.22-1 node: 7.1.0 os: linux x64

i’m new to angular2 and not sure how loadChildren is supposed to work. I upgraded coreui from angular 2.1.2 to 2.2.3 and it broke here:

Could not resolve route "app/dashboard/dashboard.module#DashboardModule" from file 
"/home/aep/kram/CoreUI-Free-Bootstrap-Admin-
Template/Angular2_CLI_Full_Project/src/app/app.module".

        children: [
            {
                path: 'dashboard',
                loadChildren: 'app/dashboard/dashboard.module#DashboardModule'
            },

what’s the path supposed to be with this relative structure?

src/app/app.module.ts
src/app/dashboard/dashboard.module.ts

i tried:

• app/dashboard/dashboard.module#DashboardModule
• dashboard/dashboard.module#DashboardModule
• …/app/dashboard/dashboard.module#DashboardModule
• …/…/dashboard/dashboard.module#DashboardModule
• src/app/dashboard/dashboard.module#DashboardModule
