bug: `'width' key must be a positive Integer` when scrolling through completion candidates

Prerequisites

• I am using the latest stable or nightly neovim version
• I am using the latest version of the plugin

Neovim Version

NVIM v0.11.5 Build type: Release LuaJIT 2.1.1741730670

care.nvim setup

require("care").setup({
        snippet_expansion = function(body)
          require("luasnip").lsp_expand(body)
        end,
        ui = {
          docs = {
            advanced_styling = true,
          },
          menu = {
            -- TODO: Add colorful-menu highlights
            -- format_entry = function(entry) end,
          },
          -- FIXME: Sometimes reports this is unavailable, maybe lazy-loading issue
          type_icons = "lspkind",
        },
      })

      local function map(keys, mapping, desc)
        vim.keymap.set("i", keys, mapping, { desc = desc })
      end

      -- Perform completion
      map("<C-Space>", function()
        require("care").api.complete()
      end, "Confirm completion")
      map("<C-y>", "<Plug>(CareConfirm)", "Confirm completion")
      map("<C-e>", "<Plug>(CareClose)", "Close completion")
      map("<C-n>", "<Plug>(CareSelectNext)", "Select next completion")
      map("<C-p>", "<Plug>(CareSelectPrev)", "Select previous completion")

      -- Documentation for current completion
      map("<C-k>", function()
        require("care").api.get_documentation()
      end)
      map("<C-f>", function()
        local care = require("care")
        if care.api.doc_is_open() then
          care.api.scroll_docs(4)
        else
          vim.api.nvim_feedkeys(vim.keycode("<c-f>"), "n", false)
        end
      end)
      map("<C-b>", function()
        local care = require("care")
        if care.api.doc_is_open() then
          care.api.scroll_docs(-4)
        else
          vim.api.nvim_feedkeys(vim.keycode("<c-b>"), "n", false)
        end
      end)
      map("<C-K>", function()
        local documentation = require("care").api.get_documentation()
        if #documentation == 0 then
          return
        end
        local old_win = vim.api.nvim_get_current_win()
        vim.cmd.wincmd("v")
        local buf = vim.api.nvim_create_buf(false, true)
        vim.bo[buf].ft = "markdown"
        vim.api.nvim_buf_set_lines(buf, 0, -1, false, documentation)
        vim.api.nvim_win_set_buf(0, buf)
        vim.api.nvim_set_current_win(old_win)
      end, "Open documentation in split")
    end,

Actual behavior

It doesn't always seem to throw the error (maybe it won't throw the error if you trigger the binding too fast?), and it does seem to scroll through the list most of the time.

Expected behavior

Navigate the completion list.

Healthcheck

Note: This error is a false positive. fzy --version returns fzy 1.1 © 2014-2025 John Hawthorn. Not sure why care can't find it.

Steps to reproduce

I am editing this file with https://github.com/onlyati/quadlet-lsp. Triggering completion on Network= throws the error.

Log

care doesn't log anything, for some reason. I suspect the error is not in care, so not caught by care, but is triggered by something care does when constructing the completion list.

Other information

The issue doesn't seem to happen unless I'm operating from a working directory that is the parent of this file. The LSP working directory, then, is one level up. This could be part of the problem, but I have also had this issue occur on another file in a different project without this quirk.

Minimal config

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    {
        "max397574/care.nvim",
        -- dependencies = {
        --     -- sources
            -- -- if you have issues with luarocks
            -- "romgrk/fzy-lua-native"
        -- },
        config = function()
            -- keymappings, `require"care.config".setup(...)`
        end
    },
  },
  -- if you have issues with luarocks
  -- pkg = { sources = { nil } },
})
