Description

I have successfully installed lua ls in my lspconfig, I have checked LspInfo and it side that the Lua language server is working and has autostart, in my cmp config, I just changed the keymap to a 'super tab' like. the lsp is working as I can see the error and warning. but as I type, the auto-completion doesn't show up.

:LspInfo

Steps to reproduce

install lspconfig, config it to:

return {
	'neovim/nvim-lspconfig',
   config = function ()
		require'lspconfig'.lua_ls.setup{}
		require'lspconfig'.pylsp.setup{}
	end
}

install luasnip, config it:

return {
	'L3MON4D3/LuaSnip',
  dependencies = { "rafamadriz/friendly-snippets" },
	version = 'v2.*',
  build = "make install_jsregexp",
  config = function ()
    require("luasnip.loaders.from_vscode").lazy_load()
  end
}

install cmp, config it.

restart nvim, the plugin is cloned, but auto-completion don't work

Expected behavior

it should show up (the auto-completion)

Actual behavior

PowerShell.2024-05-16.11-50-12.mp4

as you can see, the color scheme work, treesitter work, but not auto complete

Additional context
