Error: Cannot close last window

[yetyetanotherusername]

Describe the bug
Whenever I start neovim in my home folder and try to switch to a session with session-lens, I get the following error

Error executing vim.schedule lua callback: ...al/share/nvim/lazy/auto-session/lua/auto-session/lib.lua:196: Vim:E444: Cannot close last window

        vim/_editor.lua: in function <vim/_editor.lua:0>

To Reproduce
Steps to reproduce the behavior:

• cd to /home/username
• call up session-lens telescope window & try to switch to any saved session

cd-ing to the folder of a saved session and opening neovim there works as expected, also from there switching with session-lens works. It is only when I open neovim in my user home that switching via session-lens does not work.

Expected behavior
auto-session opens the saved session chosen via session-lens

Ah I see. One of the latest features (closing unsupported windows) doesn't seem to account for this scenario. 👍
@cameronr fyi

Second this. My case is inconsistent. Sometimes it throws an error, and sometimes it doesn't. When it throws an error, Neovim either crashes and stuck (This only happened twice today, and that was how I knew the error came from auto-session); or Neovim exits successfully without even letting me check the error.

All I did was enter Neovim and then exit it right after (No edit or anything)

My setup for auto-session

return {
  "rmagatti/auto-session", -- This plugin is for restoring session from our last work period
  config = function()
    local auto_session = require("auto-session")

    auto_session.setup({
      auto_restore_enabled = false,
      auto_session_suppress_dirs = { "~/", "~/Downloads", "~/Documents", "~/Desktop/" },
    })

    local keymap = vim.keymap

    keymap.set("n", "<leader>wr", "<cmd>SessionRestore<CR>", { desc = "Restore session for cwd" }) -- restore last workspace session for current directory
    keymap.set("n", "<leader>ws", "<cmd>SessionSave<CR>", { desc = "Save session for auto session root dir" }) -- save workspace session for current working directory
  end,
}

Specifically, the error is at this code snippet.

  vim.api.nvim_create_autocmd({ "VimLeavePre" }, {
    group = group,
    pattern = "*",
    callback = function()
      if not vim.g.in_pager_mode then
        AutoSession.AutoSaveSession()
      end
    end,
  })

Thank you guys for having a look. 🙏

In the meantime I have resorted to setting close_unsupported_windows = false in my auto-session config and everything works as expected. 👌

[cameronr]

i have a fix that wraps close_unsupported_windows in a pcall but i'm looking more closely at this.

[cameronr]

@rmagatti PR for this is #309. Let me know what you think.

[rmagatti]

Should be fixed with @cameronr's PR. Thanks, you've been a big help!
@yetyetanotherusername hopefully this fixes it for you 🙏

[yetyetanotherusername]

Can confirm the error when using close_unsupported_windows = true is fixed. Thank you!
