[coc.nvim] error on notification "doKeymap": this.engines is not iterable # map call [coc.nvim] Command error: this.engines is not iterable # command call

This warning appears wherever coc-translator is called, including :CocCommand translator.popup/echo/replace hello and nmap define in init.vim.

My system environment:

OS: WSL2-ArchWSL (Arch Linux on WSL2)
vim version: NVIM v0.4.4
node version: v15.3.0
coc.nvim version: 0.0.79-3658eda4fa
coc-translator: Current version 1.5.0 is up to date.

My init.vim:

" Translating current text in popup (CocCommand translator.*)
nmap ;t <Plug>(coc-translator-p)
vmap ;t <Plug>(coc-translator-pv)

My coc.nvim configuration:

"translator.engines": {
  "type": "array",
  "default": [
  "bing",
  "google",
  "youdao",
  "haici"
   ]
},
