Expected behavior modulo it is not recognized

Actual behavior 'mdb-navbar' is not a known element: 1. If 'mdb-navbar' is an Angular component, then verify that it is part of this module. 2. If 'mdb-navbar' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
