Errror - attempt to call field 'iter'

[sfragis]

Hi, I wanted to give your plugin a try but experienced an issue. I'm quite new to nvim so I might have written something wrong.

I'm using lazy.nvim and this is the relevant config:

{
  'doums/tenaille.nvim',
  config = function() 
    require('tenaille').setup()
  end
}

Whenever I select some text and type <Leader>" I get this error:

E5108: Error executing lua: .../share/nvim/lazy/tenaille.nvim/lua/tenaille/tenaille.lua:37: attempt to call field 'iter' (a nil value)
stack traceback:
        .../share/nvim/lazy/tenaille.nvim/lua/tenaille/tenaille.lua:37: in function 'get_selection'
        .../share/nvim/lazy/tenaille.nvim/lua/tenaille/tenaille.lua:177: in function 'wrap'
        .../share/nvim/lazy/tenaille.nvim/lua/tenaille/tenaille.lua:222: in function <.../share/nvim/lazy/tenaille.nvim/lua/tenaille/tenaille.lua:221>

I'm using nvim 0.9.4.

I get the exact same error message using nvim 0.9.5-2 and using the lazy plugin manager.

details of my tenaille.lua file, basicly the readme.md config

return {
  "doums/tenaille.nvim",

  config = function()
    local tenaille = require("tenaille")

    -- Default config
    tenaille.setup({
      -- generate default mapping for each pair using
      -- <leader>_open-character_
      -- i.e.
      -- <leader>" for double quotes ""
      -- <leader>[ for brackets []
      -- <leader>{ for curly braces {} and so on...
      default_mapping = true,
      -- supported brackets and quotes pairs
      -- ⚠ only 2 character pairs are supported
      pairs = {
        { '"', '"' },
        { "'", "'" },
        { "`", "`" },
        { "{", "}" },
        { "[", "]" },
        { "(", ")" },
        { "<", ">" },
      },
    })
  end,
}
