@sachinchaudhary1808 I have been having the same issue with ruff:

[null-ls] failed to load builtin ruff for method diagnostics; please check your config

How did you fix it?

Hi thanks for the reply -- so I guess we should re open the issue since this problem is not solved. Right?
(Pytlint can be 120x slower than ruff).

[gsavarela]

I have this on my null-ls.lua config file:

local autogroup = vim.api.nvim_create_augroup("LspFormatting", {})
local null_ls =   require('null-ls')

local opts = {
  sources = {
    null_ls.builtins.formatting.black,
    null_ls.builtins.diagnostics.mypy,
    null_ls.builtins.diagnostics.ruff,
  },
  on_attach = function(client, bufnr)
    if client.supports_method("textDocument/formatting") then
      vim.api.nvim_clear_autocmds({
        group = autogroup,
        buffer = bufnr,
      })
      vim.api.nvim_create_autocmd("BufWritePre", {
        group = autogroup,
        buffer = bufnr,
        callback = function()
          vim.lsp.buf.format({bufnr = bufnr})
        end,

      })
    end
  end,
