Added _NODE\_OPTIONS="--debug-brk --inspect'_ and started kibana using _npm start_ from my plugin source dir. After launching _chrome://inspect_, I can see Kibana server code listed in sources but not my plugin source code. How can I attach my plugin source to debugger? ---

Are you seeing in the Kibana console that optimization completed? Does the list of plugins that were optimized include your plugin? I've previously attempted to do what you're trying, but I have always given up because the optimization process takes too long to be able to work this way. I usually just use `console.log` to debug my plugin in server-side code. ---

It worked for me with `NODE_OPTIONS='--inspect --debug'`. Following is the ouput when I run `npm start`. Lazy Optimization completed and my plugin code got listed in chrome://inspect and I was able to add break points to my plugin source. The last chrome-devtools url on port 5860 worked for me. I using Kibana 5.6.1. ``` Debugger listening on port 9229. Warning: This is an experimental feature and could change at any time.

Good to know! So maybe using `--debug-brk` does something that makes it not work as well compared to `--debug` ---
