Bug: "unable to generate webapp bundle: focalboard: unable to read webapp bundle"

[MarkWieczorek]

Steps to reproduce the behavior

I downloaded the file mattermost-plugin-boards-v9.0.0.tar.gz, uncompressed it in the plugins directory and set the correct permissions for the folder. After restarting the server, the plugin doesn't load, and gives the following error

Unable to activate plugin","caller":"app/plugin.go:171","plugin_id":"focalboard","bundle_path":"plugins/boards","error":"unable to generate webapp bundle: focalboard: unable to copy webapp bundle directory: focalboard: stat plugins/focalboard/webapp/dist: no such file or directory

This is the only plugin that I am having problems installing.

Expected behavior

I would expect the plugin to load.
