Can't get format on save to work :(

[renatojf]

So I've been fighting this for a few days now, but couldn't make it work.
I have configured null-ls to format on save, but nothing happens. Even calling the format manually doesn't to anything. The debug logs show that it ran successfully, but no formatting is applied. Can someone help me understand what's wrong here?

null-ls

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

local sources = {
  null_ls.builtins.formatting.buf,
  null_ls.builtins.formatting.gofumpt,
  null_ls.builtins.formatting.goimports_reviser,
  null_ls.builtins.formatting.golines,
  null_ls.builtins.formatting.fixjson,
  null_ls.builtins.diagnostics.buf,
  null_ls.builtins.diagnostics.golangci_lint,
  null_ls.builtins.diagnostics.staticcheck,
}

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({ bufnr = bufnr })
        end,
      })
    end
  end
})

plugins.lua

{
    "neovim/nvim-lspconfig",
    
    dependencies = {
      "jose-elias-alvarez/null-ls.nvim",
      config = function()
        require "custom.configs.null-ls"
      end,
    },

    config = function ()
      require "plugins.configs.lspconfig"
      require "custom.configs.lspconfig"
    end,
  },

I am using NvChad and if anything else is needed, please lemme know :)

Try to reproduce your issue using the minimal config provided by the issue template first, if you can reproduce your issue with minimal config then it's probably null-ls issue, if not it's probably your config issue and in that case try asking NvChad first
