I am getting errors regarding webpack and visTypeTimeseries when I do 'yarn start'. These errirs appears to come from kibana and not my plugin. Note that we have just upgraded our plugin in from 7.9.3 to 7.16.3. This was working in 7.9.3.

Commands I used

```auto
yarn cache clean
yarn kbn clean
yarn kbn bootstrap
cd plugins/wind
KBN_OPTIMIZER_THEMES=v7light,v7dark yarn start

```

Errors I get

```auto
KBN_OPTIMIZER_THEMES=v7light,v7dark yarn start
yarn run v1.22.15
$ node ../../scripts/kibana --dev

Maybe is the v7 theme. Have you tried to start kibana with the v8 theme ?

Its not the theme. We got it working but must run "yarn start" within the "kibana" folder and not "kibana/plugins/wind"

It would be great to have better documentation regarding working with external plugins.

Thanks,  
Kris
