does not fold if err != nil, there will be a unexpected slide when repositioning to the original open file position

[jensenojs]

config is below.

return {
    'Snyssfx/goerr-nvim',
    config = function()

    end,
}

and i use treesitter,

        vim.opt.foldmethod = "expr"
        vim.opt.foldexpr = "nvim_treesitter#foldexpr()"
        vim.opt.foldlevel = 10

i have tried with vim.opt.foldmethod = "on", but only sliding time shorter(but it should not happen) with still no if err != nil folding. i also tried to turn off "ethanholz/nvim-lastplace" with no effect.

I'd love to try out this plugin, any help?
