Opening files in split or vertical split doesn't work

[Clish254]

I've tried to setup nnn.nvim to open files in split and vsplit but it doesn't work. Instead 0 selected is logged. Here is my config

require("nnn").setup({
  picker = {
    cmd = "nnn -o",      
    style = {
      width = 0.4,   
      height = 0.6,   
      border = "rounded"
    },
  },
  auto_open = {
    setup = "explorer",      
    tabpage = "explorer",     
    empty = true,     
    ft_ignore = {      
      "gitcommit",
    }
  },
  auto_close = false,  
  replace_netrw = "picker", 
})
local builtin = require("nnn").builtin
mappings = {
  { "<C-t>", builtin.open_in_tab },       -- open file(s) in tab
  { "<C-s>", builtin.open_in_split },     -- open file(s) in split
  { "<C-v>", builtin.open_in_vsplit },    -- open file(s) in vertical split
  { "<C-p>", builtin.open_in_preview },   -- open file in preview split keeping nnn focused
  { "<C-y>", builtin.copy_to_clipboard }, -- copy file(s) to clipboard
  { "<C-w>", builtin.cd_to_path },        -- cd to file directory
  { "<C-e>", builtin.populate_cmdline },  -- populate cmdline (:) with file(s)
}
