Describe the bug

I get an error when CoC completion is triggered

[coc.nvim]: UnhandledRejection: Cannot read properties of null (reading 'word')
TypeError: Cannot read properties of null (reading 'word')

(Happens with coc-svelte, but the backtrace points tot coc itself...)

Reproduce the bug

We will close your issue when you don't provide minimal vimrc and we can't
reproduce it

• Create file mini.lua with：

local Plug = vim.fn['plug#']

vim.call('plug#begin', vim.fn.stdpath('data') .. '/plugged')

Plug('neoclide/coc.nvim', {branch = 'release'})
Plug('coc-extensions/coc-svelte', {['do'] = 'yarn install --frozen-lockfile'})

vim.call('plug#end')

• Start (neo)vim with command: nvim -u mini.lua
• Start any completion by typing a single letter
• You get the error
