nimsuggest cannot be exected: Vim(let):E730: Using a List as a String

[anta40]

I'm on Mac M2, with vim and neovim installed via hombrew.
First I install nimlsp. For neovim, coc-settings.json is located on ~/.config/nvim/

{
  "languageserver": {
    "nim": {
      "command": "~/.nimble/bin/nimlangserver",
      "filetypes": ["nim"],
      "trace.server": "verbose",
      "settings": {
        "nim": {
          "nimsuggestPath": "/opt/homebrew/bin/nimsuggest"
        }
      }
    }
  }
}

It works.

And for vim, I copy the same coc-settings.json to my home directory. Hmm doesn't work fine
