Zed code completion not working

Nice, that solved it for me.

Also, I added the following overall config for Elixir, maybe it is useful for someone :slight_smile:

Selects the language server and configures format on save.

Most of it was taken from the zed manual

{
  "languages": {
    "Elixir": {
      "show_inline_completions": true,
      "language_servers": ["elixir-ls"],
      "format_on_save": {
        "external": {
          "command": "mix",
          "arguments": ["format", "--stdin-filename", "{buffer_path}", "-"]
        }
      }
    }
  }
}
