Ao executar os testes com o comando ng e2e é retornando o seguinte erro: Failed: Error while waiting for Protractor to sync with the page: "both angularJS testability and angular testability are undefined. This could be either because this is a non-angular page or because your test involves client-side navigation, which can interfere with Protractor's bootstrapping. See http://git.io/v4gXM for details". Alguém conseguiria me ajudar?
