At opening a file I'm having this error

[CristianArean]

I don't think it's a bug, that's why I post it here.

When I open a file neovim shows me the following error:
Error detected while processing LspAttach Autocommands for "*": Error executing lua callback: ...ck/packer/start/lspsaga.nvim/lua/lspsaga/symbol/head.lua:25: unexpected event stack traceback: [C]: in function 'nvim_create_autocmd' ...ck/packer/start/lspsaga.nvim/lua/lspsaga/symbol/head.lua:25: in function 'buf_watcher' ...ck/packer/start/lspsaga.nvim/lua/lspsaga/symbol/head.lua:180: in function <...ck/packer/start/lspsaga.nvim/lua/lspsaga/symbol/head.lua:165> [C]: in function 'nvim_exec_autocmds' /usr/share/nvim/runtime/lua/vim/lsp.lua:1531: in function '_on_attach' /usr/share/nvim/runtime/lua/vim/lsp.lua:1358: in function '' vim/_editor.lua: in function <vim/_editor.lua:0>

I don't really know why. Can someone give me a hand?

here is my lspsaga config file:

local status, saga = pcall(require, "lspsaga")
if (not status) then return end

saga.setup({
  ui = {
    winblend = 10,
    border = 'rounded',
    colors = {
      normal_bg = '#002b36'
    }
  }
})

local diagnostic = require("lspsaga.diagnostic")
local opts = { noremap = true, silent = true }
vim.keymap.set('n', '<C-j>', '<Cmd>Lspsaga diagnostic_jump_next<CR>', opts)
vim.keymap.set('n', 'gl', '<Cmd>Lspsaga show_diagnostic<CR>', opts)
vim.keymap.set('n', 'K', '<Cmd>Lspsaga hover_doc<CR>', opts)
vim.keymap.set('n', 'gd', '<Cmd>Lspsaga lsp_finder<CR>', opts)
-- vim.keymap.set('i', '<C-k>', '<Cmd>Lspsaga signature_help<CR>', opts)
vim.keymap.set('i', '<C-k>', '<cmd>lua vim.lsp.buf.signature_help()<CR>', opts)
vim.keymap.set('n', 'gp', '<Cmd>Lspsaga peek_definition<CR>', opts)
vim.keymap.set('n', 'gr', '<Cmd>Lspsaga rename<CR>', opts)

-- code action
local codeaction = require("lspsaga.codeaction")
vim.keymap.set("n", "<leader>ca", function() codeaction:code_action() end, { silent = true })
vim.keymap.set("v", "<leader>ca", function()
  vim.fn.feedkeys(vim.api.nvim_replace_termcodes("<C-U>", true, false, true))
  codeaction:range_code_action()
end, { silent = true })

here a error that's giving me when I do gp over a function:

of course if I'm not giving enough information to solve it feel free to ask. Thank you!
