Hi,

I tried using the Kibana network plugin on my Ubuntu 18 version by downloading the latest version of the network plugin tar.gz file as the Kibana version on my system is 7.6  
But when I start the Kibana service - it fails with the below mentioned error in the logs:

\*\*\> FATAL Error: Optimizations failure.

> ERROR in ./plugins/network\_vis/public/network\_vis.js  
> Module not found: Error: Can't resolve 'ui/vis/vis\_factory' in '/usr/share/kibana/plugins/network\_vis/public'

Below is the details of package.json file

I am unable to get a proper resolution for it from anywhere on the google or the digitalocean website.

Can anyone help me here with this issue ? How can this be resolved and what changes will I have to make?

Hi, I have the same issue than you,

The plugin doesn't working for now on 7.6.0 version, you can try to downgrade to 7.4.0

The best would be to contact the plugin creator, if they have a github page or something. It's not created or maintained by us.

I tried contacting the dev and also have created an issue there, but no response from the dev yet.  
Could you help if you have any idea about the issue and the solution for it ?
