automatic_installation not working

[kjurl]

Using Nvchad. Here is my custom/plugins.lua file:

...
{
    "jay-babu/mason-null-ls.nvim",
    event = { "BufReadPre", "BufNewFile" },
    dependencies = {
      "jose-elias-alvarez/null-ls.nvim",
      "williamboman/mason.nvim",
    },
    opts = {
      ensure_installed = nil,
      automatic_installed = true,
    },
    config = function(_, opts)
      require("mason-null-ls").setup(opts)
      require "custom.configs.null-ls"
    end,
},
...

and here is the custom/configs/null-ls.lua

local null_ls = require "null-ls"
local b = null_ls.builtins

local sources = {
  b.formatting.stylua.with {
    extra_args = { "--config-path", vim.fn.expand "~/.config/nvim/.stylua.toml" },
  },
  b.diagnostics.write_good.with {
    diagnostics_postprocess = function(diagnostic)
      diagnostic.severity = diagnostic.message:find "really" and vim.diagnostic.severity["ERROR"]
        or vim.diagnostic.severity["WARN"]
    end,
  },
  -- bash
  b.formatting.shfmt,
  b.code_actions.shellcheck.with {
    diagnostic_config = {
      -- see :help vim.diagnostic.config()
      underline = true,
      virtual_text = false,
      signs = true,
      update_in_insert = false,
      severity_sort = true,
    },
    -- will show code and source name
    diagnostics_format = "[#{c}] #{m} (#{s})",
  },
  -- webdev
  b.formatting.prettier.with {
    extra_filetypes = { "astro", "toml" },
    -- condition = function(utils)
    --   return utils.root_has_file "package.json"
    --     or utils.root_has_file ".prettierrc"
    --     or utils.root_has_file ".prettierrc.json"
    --     or utils.root_has_file ".prettierrc.js"
    -- end,
  }, -- so prettier works only on these filetypes
  b.diagnostics.eslint.with {
    condition = function(utils)
      return utils.root_has_file "package.json"
        or utils.root_has_file ".eslintrc.json"
        or utils.root_has_file ".eslintrc.js"
    end,
    filter = function(diagnostic)
      return diagnostic.code ~= "prettier/prettier"
    end,
  },
  -- python
  b.diagnostics.mypy.with {
    extra_args = function()
      local virtual = os.getenv "VIRTUAL_ENV" or os.getenv "CONDA_DEFAULT_ENV" or "/usr"
      return { "--python-executable", virtual .. "/bin/python" }
    end,
    prefer_local = true,
  },
  b.formatting.black,
  b.formatting.isort,
}

local augroup = vim.api.nvim_create_augroup("LspFormatting", {})

require("null-ls").setup {
  debug = true,
  sources = sources,
  on_attach = function(client, bufnr)
    if client.supports_method "textDocument/formatting" then
      vim.api.nvim_clear_autocmds { group = augroup, buffer = bufnr }
      vim.api.nvim_create_autocmd("BufWritePre", {
        group = augroup,
        buffer = bufnr,
        callback = function()
          vim.lsp.buf.format { async = false }
        end,
      })
    end
  end,
}

I cannot get mason-null-ls to automatically install mypy. Any help is appreciated.

Makes sense it wouldn't work. Should be automatic_installation
