Problem getting example-App Plugin work

Hi,

I’m testing the example-app on grafana 6.2.0 but i failed to get it work. the app is not even recognized as installed. On grafana 6.1.6 it works. but the react Pages are not rendered.

the Project is on github: https://github.com/a-siewe/grafana-example-app

Would be nice to get some help

Thanks
Armel
