Ionic 2.0 Application: on load - failed to decode downloaded font, Roboto Large and Medium font

We are working on a Meteor 1.3, Angular 2.0 and Ionic 2.0 application. The application works and loads properly, however we get the following error in our console:

“Failed to decode downloaded font:
http://localhost:3000/fonts/roboto-regular.ttf” (as well as roboto-large.woff, roboto-medium.ttf, etc).

Additionally, we believe we are having errors with the Ionicons, and this is related to the above issue. For example, in a search bar that we have in the application, when we click inside the search box, an ice cream cone appears as the icon which is not expected.

Does anyone know how to fix these items?

Thank you
