EDIT: Changed title after some more debugging.

Does anyone know a way to debug the on_attach function so I can fix this problem?

I wanted to log what is coming as a client and buffnr.

Language client log: /Users/dantxal/.local/state/nvim/lsp.log
Detected filetype:   typescript

1 client(s) attached to this buffer: 


Client: null-ls (id: 1, pid: 5001, bufnr: [16])
	filetypes:       javascriptreact, javascript, json, yaml, css, jsonc, scss, handlebars, markdown, graphql, html, vue, less, typescript, typescriptreact, python
	autostart:       false
	root directory:  /Users/dantxal/projects/webtrip-wts-wintour-api
	cmd:             nvim

Configured servers list: jsonls, sumneko_lua

The list of servers that can be used is in lua/user/lsp/configs.lua variable servers. You need to update that variables for the new server to be configured and therefore available.

How can i setup LSP for new languages. When I add javascript, java, ruby, golang etc it didn't work ?
