[Bug]: attempt to call field 'iter' (a nil value)

[nicktify]

Description

Hello. I'm having a problem after installation.

Just after installing, I open a .js file and the error attempt to call field 'iter' (a nil value) appears.

I search for the function iter in the codebase of the dropbar .lua files and comment the following code and all works perfectly.

The code is in lua/sources/lsp.lua line 288

-- Code uncommented doesn't work
  for idx, symbol in vim.iter(lsp_symbols):enumerate():rev() do
    if cursor_in_range(cursor, symbol.range) then
      table.insert(
        dropbar_symbols,
        utils.to_dropbar_symbol(unify_document_symbol(symbol, lsp_symbols, idx))
      )
      if symbol.children then
        convert_document_symbol_list(symbol.children, dropbar_symbols, cursor)
      end
      return
    end
  end

--  This code commented, all works perfectly
  -- for idx, symbol in vim.iter(lsp_symbols):enumerate():rev() do
  --   if cursor_in_range(cursor, symbol.range) then
  --     table.insert(
  --       dropbar_symbols,
  --       utils.to_dropbar_symbol(unify_document_symbol(symbol, lsp_symbols, idx))
  --     )
  --     if symbol.children then
  --       convert_document_symbol_list(symbol.children, dropbar_symbols, cursor)
  --     end
  --     return
  --   end
  -- end

Sorry about the inconvenience! I made a mistake about the nvim version required for this plugin, actually it is required to have nvim nightly (>= 0.10.0) for dropbar.nvim to work since the vim.iter module is new feature introduced in nvim nightly. Thanks for reporting.
