[BUG] when I run checkhealth -> attempt to call field 'debug' (a nil value)

[1Jo1]

Description

According to the README, I used the following configuration:

use {
  'rmagatti/auto-session',
  config = function()
    require("auto-session").setup {
      suppressed_dirs = { "~/", "~/Projects", "~/Downloads", "/"},
    }
  end
}

when I run :checkhealth I'm getting this error

auto-session: require("auto-session.health").check()

vim options ~
- OK vim.o.sessionoptions

Lazy.nvim settings ~
- Lazy.nvim not loaded

Config ~
- OK 
  {}

General Info ~
- ERROR Failed to run healthcheck for "auto-session" plugin. Exception:
  ...pack/packer/start/auto-session/lua/auto-session/init.lua:333: attempt to call field 'debug' (a nil value)

Expected Behavior I expect :checkhealth to pass without any issues.

Checkhealth Output See the section above.

Environment Details

• Output of set sessionoptions?: Not working, unsure of the cause.
• OS (e.g., uname -a): 6.10.10-arch1-1
• Neovim version (nvim --version): NVIM v0.10.1

Additional Context Even after setting root_dir, which should not be nil, it still returns a nil value.

Hmm, that is quite strange. Looking at the code, I'm struggling to see how root_dir is ending up nil. I just tested a default packer install and it works as expected (init.lua):

local ensure_packer = function()
  local fn = vim.fn
  local install_path = fn.stdpath("data") .. "/site/pack/packer/start/packer.nvim"
  if fn.empty(fn.glob(install_path)) > 0 then
    fn.system({ "git", "clone", "--depth", "1", "https://github.com/wbthomason/packer.nvim", install_path })
    vim.cmd([[packadd packer.nvim]])
    return true
  end
  return false
end

local packer_bootstrap = ensure_packer()

return require("packer").startup(function(use)
  use("wbthomason/packer.nvim")
  -- My plugins here
  -- use 'foo1/bar1.nvim'
  -- use 'foo2/bar2.nvim'

  use({
    "rmagatti/auto-session",
    config = function()
      require("auto-session").setup({
        suppressed_dirs = { "~/", "~/Projects", "~/Downloads", "/" },
      })
    end,
  })

  -- Automatically set up your configuration after cloning packer.nvim
  -- Put this at the end after all plugins
  if packer_bootstrap then
    require("packer").sync()
  end
end)

Can you share more of your packer config to see if there's something else going on?

[cameronr]

I looked at it a bit more closely and I can reproduce the behavior you're seeing if auto-session's setup function is never called (that results in Lib never being initialized which is the error you're seeing in init.lua:333).

So there must be something going on with your packer config where it's not actually calling the config function you have in your auto-session use block. I don't know packer very well but if you share your packer config, I'm happy to take a look.

not really familiar with packer plugin, maybe I messed up my packer config...I'm gonna try to call setup function in the init

I looked at it a bit more closely and I can reproduce the behavior you're seeing if auto-session's setup function is never called (that results in Lib never being initialized which is the error you're seeing in init.lua:333).

So there must be something going on with your packer config where it's not actually calling the config function you have in your auto-session use block. I don't know packer very well but if you share your packer config, I'm happy to take a look.

I ended up putting the setup function in init.lua, and it works perfectly. You were right—it’s an issue with Packer. For some reason, Packer isn’t calling the config function. Maybe it’s a sign to switch to lazy loading, haha

I just switched to lazy package manager haha so much fast hehe, auto session it works perfectly :)
