How can I use "nvim-lsp-installer.health".check?

[joaothallis]

In my init.lua:

require("nvim-lsp-installer.health").check()

Error when I open nvim:

Error detected while processing /home/joao/.config/nvim/init.lua:
E5113: Error while calling lua chunk: Vim(let):E121: Undefined variable: s:output

You're not supposed to import that file yourself, it's done by Neovim when running :checkhealth!
