Operating system/version

How to reproduce the issue

cat mini.lua

-- Use Vim packages install the plugin, also work with some plugins manager such as packer.nvim
vim.o.packpath = '~/.local/share/nvim/site'
vim.cmd('packadd promise-async')
vim.cmd('packadd nvim-ufo')

-- Setting
vim.o.foldcolumn = 'auto'
vim.o.foldlevel = 99
vim.o.foldlevelstart = -1
vim.o.foldenable = true

local ufo = require('ufo')
ufo.setup({
  close_fold_kinds_for_ft = {
    default = { "imports" },
  },
  open_fold_hl_timeout = 0,
  preview = {
    win_config = {
      border = "rounded",
      winblend = 0,
    },
  },
  provider_selector = function(_, filetype, buftype)
    -- use nested markdown folding
    if filetype == "markdown" then
      return ""
    end

    -- return ftMap[filetype] or { "treesitter", "indent" }
    -- return { "treesitter", "indent" }
    local function handleFallbackException(bufnr, err, providerName)
      if type(err) == "string" and err:match "UfoFallbackException" then
        return require("ufo").getFolds(bufnr, providerName)
      else
        return require("promise").reject(err)
      end
    end

    -- only use indent until a file is opened
    return (filetype == "" or buftype == "nofile") and "indent"
      or function(bufnr)
        return require("ufo")
          .getFolds(bufnr, "lsp")
          :catch(function(err)
            return handleFallbackException(bufnr, err, "treesitter")
          end)
          :catch(function(err)
            return handleFallbackException(bufnr, err, "indent")
          end)
      end
  end,
})
vim.keymap.set('n', 'zR', ufo.openAllFolds)
vim.keymap.set('n', 'zM', ufo.closeAllFolds)

nvim --clean +'so mini.lua'

  1. Open a go file

Expected behavior

The code above should open a Go file with the imports folded.

When UFO works:
image

Actual behavior

The code works most of the time, but sometimes when I open a file the folded code has a 0 instead of the default text and I get a lot of index out of bounds error.

Folded code:

0
}

Error

Error in decoration provider ufo.end:

Which buffer is index out of bounds from your log? If you load ufo without lazy event, is there an issue?

It seems that the issue doesn't happen if I use lazy=false, however, this issue started to happen in the last month because I have been using BufRead for almost a year without issues.

Which buffer is index out of bounds from your log? What's the content? Actually, I have no idea to fix.

In this example my buffer is the bufnr 2.

Untitled.mov
