I'm doing a plugin migration from 6.1.x to 6.4.x
All plugin works well in 6.1.x
I can get es module in service dependencies priviously, but it is missing in 6.4.x version(which means it is undefined)
$http $q and configService(which is a custom service I defined) have corresponding values
so what should I do to make es show in the service module?
Is there a way to inject it ?
