Unable to format with Rubocop

[anlek]

When I use the keyboard shortcut, I get the following error in my console:

Unable to open /Users/andrew/Library/Application Support/Sublime Text 3/Packages/Codefmt/Codefmt.sublime-settings
git: tracking working dir /Users/andrew/Library/Application Support/Sublime Text 3/Packages/User
Traceback (most recent call last):

  File "/Users/andrew/Library/Application Support/Sublime Text 3/Installed Packages/Codefmt.sublime-package/utils.py", line 122, in find_matching_formatters
TypeError: 'NoneType' object is not iterable

My config looks like this:

{
  "format_on_save": true,
  "debug": true,
  "rubocop": {
    // The command that will be executed for format files.
    "command": [
      "/Users/andrew/.asdf/shims/rubocop",
      "--auto-correct-all",
      "--config",
      "$config",
      "$file"
    ],

    // The scopes that will be considered when formatting
    "scopes": ["source.ruby", "source.ruby.rails"],

    // Additional flags when running in debug mode.
    "debug": ["--debug", "--extra-details"],

    // When no custom config file exists, use a default config file.
    "default_config": null,

    // Config files that will be looked up on the root of the project.
    "config_files": [".rubocop.yml"]
  },
  "formatters": [
    "rubocop",
  ]
}

However, I've tried running the code with my settings looking like: {}

I believe this issue is actually that it can't find the /Users/andrew/Library/Application Support/Sublime Text 3/Packages/Codefmt/Codefmt.sublime-settings. As the Codefmt is not there for me.

I manually created the Codefmt folder and that part of the error goes away,
However, I still get:
