We have recently upgraded from Kibana 8.6.2 to 8.8.0. We are having issues launching the dev environment which now requires the use of `yarn dev --watch` as per [doc](https://www.elastic.co/guide/en/kibana/current/plugin-tooling.html) ```auto kbujold@yow-kbujold-lx-vm2:wind$ yarn dev --watch yarn run v1.22.19 $ yarn plugin-helpers dev --watch $ node ../../scripts/plugin_helpers dev --watch info deleting the target folder info running @kbn/optimizer in watch mode (use CTRL+C to quit) │ERROR Using kebab-case for css properties in objects is not supported.

It appears the issue was with 'common/index.ts' missing in the plugin directory. This file must exist and can be empty. ---
