null-ls setup function with error 'expects a maximum of 0 argument(s) but instead it is receiving 1'

[mswdevsla]

Hello, I'm beginer of Neovim. I'm going to install and set up the null-ls plug-in on neovim. But when I was configuring, I can't use null-ls setup function.

local status, null_ls = pcall(require, "null-ls")
if not status then
  return
end

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

local lsp_formatting = function(bufnr)
  vim.lsp.buf.format({
    filter = function(client)
      return client.name == "null-ls"
    end,
    bufnr = bufnr,
  })
end

local formatting = null_ls.builtins.formatting

null_ls.setup({
  sources = {
    formatting.prettier,
    formatting.stylua,
    null_ls.builtins.diagnostics.eslint_d.with({
      diagnostics_format = "[eslint] #{m}\n(#{c})",
    }),
    null_ls.builtins.diagnostics.fish,
  },
  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()
          lsp_formatting(bufnr)
        end,
      })
    end
  end,
})

Then press the 'gd' key to go to the setup function definition and go to the eslint plug-in.

eslint.lua file like this (~/.local/share/nvim/site/pack/packer/start/eslint.nvim/lua/eslint/null-ls.lua)

local ok, null_ls = pcall(require, "null-ls")

local options = require("eslint.options")
local utils = require("eslint.utils")

local function eslint_enabled()
  return utils.config_file_exists()
end

local M = {}

function M.setup()
  if not ok then
    return
  end
  ...
end

How can I fix this?

Sorry, I don't understand the issue. The error you are describing sounds like it comes from lua-language-server, in which case you can ignore it. I don't understand what's going on with ESLint at all - you are setting up the null-ls source and also running some other plugin?
