doesn't work when ansible-lint parseable is enabled

[twouters]

When parseable mode is enabled for ansible-lint (parseable: true in .ansible-lint) the plugin is unable to parse ansible-lint's output.

I'm not sure if this is an issue of this plugin, or ansible-language-server.

[coc.nvim] Could not parse ansible-lint output. Please check your ansible-lint installation & configuration. More info in 
`Ansible Server` output.

output (:CocCommand workspace.showOutput) when parseable is enabled:
