Dear all,

I am using kibana 6.2.4 and would like to install a plugin which is called mapster ([https://github.com/OmniCyberSecurity/mapster](https://github.com/OmniCyberSecurity/mapster)). When I try to run, it show following error message. Any idea? Thanks

It's possible that the plugin isn't yet compatible Kibana 6.2.4. You can see an issue like that here: [https://github.com/OmniCyberSecurity/mapster/issues/1](https://github.com/OmniCyberSecurity/mapster/issues/1)

You should follow up with them.
