angularls with root_dir setup does not work in combination with mason-lspconfig

[nicolaric-akenza]

Problem description

i now spent hours trying to set up my angularls with my Nx project. For this, a different value for the root_dir attribute needs to be set (angular.json not available, instead nx.json should be used).
i opened an issue for that on nvim-lspconfig repo (neovim/nvim-lspconfig#3237). it turns out, that the angularls is working correct, if i don't use williamboman/mason-lspconfig.nvim.

here is my setup:

return {
  {
    "williamboman/mason.nvim",
    lazy = false,
    config = function()
      require("mason").setup()
    end,
  },
  {
    "williamboman/mason-lspconfig.nvim",
    lazy = false,
    opts = {
      auto_install = true,
    },
  },
  { "tjdevries/vlog.nvim" },
  {
    "neovim/nvim-lspconfig",
    lazy = false,
    config = function()
      local lspconfig = require('lspconfig')
        lspconfig.angularls.setup {
          root_dir = function(fname)
            vim.notify('Root dir called', vim.log.levels.INFO)
            local util = require 'lspconfig.util'
            return util.root_pattern 'nx.json'(fname) or util.find_git_ancestor(fname)
          end,
      }
    end,
  },
}```
