bug: "attempt to call method 'flatten' (a nil value)"

[smsossah]

Did you check docs and existing issues?

• I have read all the lazy.nvim docs
• I have searched the existing issues of lazy.nvim
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

nvim v.0.10.0-dev-1471+ga8aebcff5-Homebrew

Operating system/version

MacOS Sonoma 14.4.1

Describe the bug

I am attempting to load the Mofiqul/vscode.nvim, and am getting a failure: ".local/share/nvim/lazy/lazy.nvim/lua/lazy/help.lua:16: attempt to call method 'flatten' (a nil value)". I noticed that there were some changes added in today's release in regards to the flatten() method and was wondering if this is a bug and if so how I could go about fixing it? Here's a screenshot

The colorscheme still loads but when I run the Lazy Update command I get the error described above.

(update) I realized I get the same error when loading other plugins like nvim-tree

Steps To Reproduce

Install lazy
Attempt to load https://github.com/Mofiqul/vscode.nvim :
return {
'Mofiqul/vscode.nvim'
config = function()
vim.cmd([[ colorscheme vscode ]])
end,
}

I've also tried other alternatives which worked previously but it leads to the same failure

Expected Behavior

I would expect the update command to run without failures when running :Lazy and selecting "U" to update

Repro

No response

either use a recent nightly, or a stable neovim versions.
I'm not going to support old nightlies

Could this be caused by the latest neovim 0.10.0 release (out yesterday?) This seems to reproduce in my 0.10.0 installation while it does not show up on the v0.9.5.

[MichaelC001]

some error!

[max397574]

as folke said above
you're using an old nightly version
either update to 0.10 stable or 0.11 nightly

[smsossah]

@dfszb @MichaelC001 upgrading to 0.11 worked for me!

[ehrktia]

sorry @smsossah upgrading to 0.11 did not help for me .
Had tried both 0.10 and 0.11 nightly as well
still having same error

if it helps

nvim --version                                                                                                                                                                       18:21:24

lazy version

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    -- "--branch=main", -- latest stable release
    "--version=v10.20.5",
    lazypath,
  })

will try again to check if i missed anything

That's strange, I assumed it was a bug with 0.10.0 once I got it working on another version. Were you able to get it working or is it still causing the issue @ehrktia? Aside from changing versions I'm not sure what else could fix it since I'm fairly new to neovim/lazy

there is a version check in nvim-lspconfig neovim/nvim-lspconfig#3172 (comment)
