Vista does not work on MacVim

[ubaldot]

Describe the bug
When opening Vista the sidebar opens but it is empty.
Furthermore, I cannot see anything on the status line (I am using vim-airline).

Environment:

• OS: macOs Ventura
• Vim/Neovim version: Vim 9.0
• This plugin version: 33774af
• I'm using universal-ctags: I don't have any tags as I am using LSP.
• I'm using some LSP client:
  • Related Vim LSP client: ALE
  • The Vim LSP client version: 3.2.0
  • Have you tried updated to the latest version of this LSP client: Yes

Run :Vista from the command line

Expected behavior
I expected to see all my file structure

Actual behavior
The sidebar is empty

UPDATE: I just discovered that I either need a ctags file or I can rely on ALE. However, the layout when using ALE is not really nice (and due to that not very useful).
