"rubocop failed with code=2" error when saving a file in VSCode

Your environment

• vscode-ruby version: 0.22.3
• Ruby version: tried with 2.6.2 and 2.5.1
• Ruby version manager (if any): rvm 1.29.7 (latest)
• VS Code version: 1.33.1
• Operating System: MacOS Mojave 10.14.4
• Using language server? I believe I am. 😃

Expected behavior

Rubocop lints the file and autofixes

Actual behavior

error popup when running on 2.6.2

No linting/autofixing when running on 2.5.1 or 2.6.2

Here is my settings.json:

{
  "editor.wordWrap": "on",
  "editor.tabSize": 2,
  "git.confirmSync": false,
  "editor.detectIndentation": false,
  "editor.formatOnSave": true,
  "workbench.startupEditor": "newUntitledFile",
  // "editor.parameterHints": false,
  "git.autofetch": true,
  "window.zoomLevel": 0,
  "ruby.intellisense": "rubyLocate",
  "ruby.lint": {
    "rubocop": {
      "lint": true,
      "rails": true
    }
  },
  "ruby.useLanguageServer": true,
  "[ruby]": {
    "editor.formatOnSave": true
  },
  "ruby.format": "rubocop",
  "editor.formatOnSaveTimeout": 1500
}

When I’m in a workspace for a ruby 2.6.2 project, I get the error popup and it doesn’t lint. When I’m in a workspace for a ruby 2.5.1 project, I don’t get the error popup, but it still doesn’t lint.

@wingrunr21 Ah, didn’t know about that page. Still, on a failing rubocop format:

…Ruby: Show Language Server Output Channel doesn’t seem to be defined:

…and Ruby: Show Output Channel show an empty page:

If you want I can try and make a reproduction. Specifically this repo requires bundler, so I set "ruby.useBundler": false, to get this error.

Was there a resolution to this? I’m seeing the same behaviour. When I run in the terminal, it corrects the problem and exits with a code of 0. I haven’t figured out how to turn on the verbose logging (fairly new to vscode) so I don’t see anything in the output tab.
