Hi there,

So I created a Kibana plugin for version 7.0  
However, it turns out I will be using version 6.5.

What's the easiest way to make the plugin compatible with that version?  
I'm also using version 7 of the Elasticsearch JS client.

Regards,  
Dilshan

What issues are you seeing when you try to load your plugin in 6.5?

I get the following error:

 ![Capture](https://us1.discourse-cdn.com/elastic/original/3X/5/1/51d37c227313cf0b0441586e9f2ce14f7d9aa40e.png)

This error doesn't occur when I try to install it in version 7.0

Coincidentally, the error is happening with code (written in typescript) I've copied from the [EUI Github repository](https://github.com/elastic/eui).

When I try installing it again, it says `Plugin alerts already exists, please remove before installing a new version`.
