Elastic Stack Kibana

Hello,

I used Kibana plugin generator to create a new App plugin.
When running the plugin inside kibana, i got this error in Chrome console.
The plugin is working with no issue, just want to understand how i can fix this issue.

I was getting this error related to es service, fixed by adding import 'ui/autoload/modules'; into app.js (Reference to https://www.elastic.co/guide/en/kibana/current/development-modules.html)
