E5108: Error executing lua: cokeline/lua/cokeline/buffers.lua:94: attempt to call method 'enumerate' (a nil value)

Hi, I'm getting the following error, when hovering with the mouse over a buffer with vim.opt.mousemoveevent = true

E5108: Error executing lua: ...vim/site/pack/lazy/opt/cokeline/lua/cokeline/buffers.lua:94: attempt to call method 'enumerate' (a nil value)

When disabling the option, I still get the error when opening vim, but from a different source:

I'm running lunarvim release-1.3/neovim-0.9-d1c1bace and neovim v0.9.4

This is my lunarvim (bare minimum testing) config.lua

Have you updated plenary.nvim anytime recently? That's the only thing I can think of, enumerate definitely exists. I'll look into this tomorrow if you can still reproduce with the latest version of plenary.

At some point I can drop plenary and just use vim.iter, but that's still too new and would cut off too many users :/

[Zombiefleischer]

plenary.nvim was also installed with lazy so I think it's the latest version

● plenary.nvim 0.11ms   neo-tree.nvim
dir    /home/zombiefleischer/.local/share/lunarvim/site/pack/lazy/opt/plenary.nvim
url    https://github.com/nvim-lua/plenary.nvim
branch master
commit 9ac3e95
readme README.md
cmd      PlenaryBustedFile   PlenaryBustedDirectory

... when I check the commit on github it's from Apr. 10. ...

[Zombiefleischer]

Lunarvim installs this plugin with this line:

{ "nvim-lua/plenary.nvim", cmd = { "PlenaryBustedFile", "PlenaryBustedDirectory" }, lazy = true },

So no version is specified and I don't quite understand which version lazy defaults to...

[willothy]

It should update to the latest version as long as you run :Lazy update or :Lazy sync somewhat regularly.

... when I check the commit on github it's from Apr. 10. ...

You'll need a newer version - you can update it individually with :Lazy update plenary.nvim.

[Zombiefleischer]

I run the update almost daily and it says

● plenary.nvim 0.11ms   neo-tree.nvim     ■ already up to date 

[willothy]

Have you tried :Lazy sync?

[Zombiefleischer]

yes

[willothy]

Hmm, not sure why it's not updating then, maybe it's worth opening an issue on the lazy.nvim repo? This isn't a cokeline issue; I'm happy to help however I can, but it seems like an issue with your config.

[Zombiefleischer]

I need to specifiy commit = '*' and now I have the latest version... weird

[willothy]

Strange, could be an issue with Lazy. You definitely don't normally need to specify a commit. Glad you got it working though! I'll close this now but feel free to reopen if you run into more issues :)
