Describe the bug

I'm not really sure how to reliably reproduce this.
If I leave an nvim session over night, I will notice this pretty reliably.
Restarting nvim will fix the issue.

How to reproduce?

1. Leave a note open for 24h
2. :ZkNotes
3. Get error.

Neovim configuration

There's a lot in there and multiple files.
I'm not sure what to post.
Here's the zk-nvim specific file (telescope):


require("zk").setup({
  -- Can be "telescope", "fzf", "fzf_lua" or "select" (`vim.ui.select`).
  -- It's recommended to use "telescope", "fzf" or "fzf_lua".
  picker = "telescope",

  lsp = {
    -- `config` is passed to `vim.lsp.start_client(config)`
    config = {
      cmd = { "zk", "lsp" },
      name = "zk",
      -- on_attach = ...
      -- etc, see `:h vim.lsp.start_client()`
    },

    -- Automatically attach buffers in a zk notebook that match the given filetypes.
    auto_attach = {
      enabled = true,
      filetypes = { "markdown" },
    },
  },
})

-- Create a new note after asking for its title.
vim.keymap.set("n", "<leader>zn", function()
  local title = vim.fn.input("Title: ")

  require("zk.commands").get("ZkNew")(
    {
      dir = "unsorted",
      title = title,
    })
end)

-- Open notes associated with the selected tags.
vim.keymap.set("n", "<leader>zt", function()
  require("zk.commands").get("ZkTags")(
    {
      sort = "modified",
    })
end)

-- Open notes, recently modified first.
vim.keymap.set("n", "<leader>zo", function()
  require("zk.commands").get("ZkNotes")({
      sort = { "modified" },
    })
end)

### Environment

Honestly, I don't see how this class of error could be caused by zk-nvim but any experiences or ideas would be useful in debugging.

[tjex]

I've also experienced this. And also don't know how to recreate it consistently 😮‍💨

By feel, it's an issue with the lsp and I think it happens when the line numbers in the document change, but the lsp doesn't get that update.

I say "by feel", because it almost seems similar to a bug I encountered with formatter.nvim, where this was the case.

[blastmaster]

I also see this issue, not necessarily after a day but after some time.

[deeengan]

if I try to do zkNewFromTitleSelection/zkNewFromContentSelection I get "attempt to perform arithmetic on a nil value"

[tjex]

@deeengan every time? Are you running the latest version of zk-nvim and which version of neovim are you on?

[tjex]

Update, a similar issue got closed that was to do with the neovim version (even though the errors were speaking zk-nvim lanuage).

So be sure to update to latest everything: zk, zk-nvim and neovim.

[deeengan]

@tjex it seems to be every time. i will update this week on unstable. i'm a bit behind on my versions now. i think it will be ok!
