Losing my lang-locale from the url on state.go

[jrmcdona]

I am injectin lang-locale (ie. "en-GB") into my URL.

I have this abstract route in my App.js config that has a url param for the lang-locale. When I run state.go('app.index') I am losing my lang-locale.

Such as this sequence here:

1. www.mysite.com/en-us
2. state.go hits
3. I end up here www.mysite.com

$stateProvider.state('app', {
                abstract: true,
                url: '/{lang:(?:en-US)}',
                template: '<ui-view=main/>'
            })

Then in my home module I have a child state set up.

$stateProvider.state('app.index', {
            url: '',
            views: {
                "main": {
                    controller: 'homeController',
                    templateUrl: '/Scripts/app/home/views/home.html'
                }
            },
            resolve: {},
            data: {
                pageTitle: ''
            }
        })

$state.go('app.index') is my app.js run method.

I am trying to follow this article https://fadeit.dk/blog/2015/03/30/angular-translate-ui-router-seo/ but he doesn't seem to have this issue that I see.

Any help would be great while I keeping digging at it.

Thanks

This was the issue. Bad parameter
url: '/{lang:(?:en-US)}',
