E121: undefined variable: g:vista_default_executive in MacVim

[ubaldot]

Describe the bug I have the following lines in my .gvimrc

Vista! Current function
function! NearestMethodOrFunction() abort
    return get(b:, 'vista_nearest_method_or_function', '')
endfunction

augroup FuncNameGet
    autocmd!
    autocmd GUIEnter * call vista#RunForNearestMethodOrFunction()
augroup END

" The error won't appear if I rename the .gvimrc in .vimrc, so I am considering this as temporary solution.

Environment:

• OS: Mac OS X
• Vim/Neovim version: Vim 9.0
• This plugin version: 33774aff5d8b224f24c2e4c6015c613c1a17bf74
• I'm using some LSP client:
  • Related Vim LSP client: ALE
  • Have you tried updated to the latest version of this LSP client: Yes

Vista info

:Vista info command does not work.

1. Just open MacVim and be sure that you are using a .gvimrc file (not a .vimrc file)
