Great article, thank you.

I get this error and I couldn't fix it.

INFO Launching Electron...

(node:15396) ExtensionLoadWarning: Warnings loading extension at C:\Users\helio\AppData\Roaming\mytest\extensions\nhdogjmejiglipccpnnnanhbledajbpd: Unrecognized manifest key 'browser_action'. Unrecognized manifest key 'update_url'. Permission 'contextMenus' is unknown or URL pattern is malformed. Cannot load extension with file or directory name _metadata. Filenames starting with "_" are reserved for use by the system.

How to fix? Could help me?
