coc-eslint: [coc.nvim] Failed to load the ESLint library for the document test.js

I’m just now getting more “serious” about using Coc in my development machine - and I’m trying to use this extension as a replacement for ALE by suggestion from this article but unfortunately I’m getting some pretty buggy behavior.

When I load a javascript file (any file) I see warnings that are legit warnings (like the neovim “sign” / gutter indicator is there) but I see the error in this issue summary at the bottom

However, if I play around enough (not sure what triggers it, but spamming $ and 0 in normal mode on a line where a sign exists eventually triggers the expected warning (and btw this one in particular I’d love to turn off but I realize its an existing annoyance for others):

I did try `:CocUpdateSync and got this output:

Is that warning anything special?

I’d greatly appreciate any help here 😃
