Warnings when executing Rubocop from a specified `BUNDLE_GEMFILE`

[murshed-panorama]

Overview

I'm using GitHub Codespaces with VS Code and have the Rubocop extension installed in my remote Codespace environment. When I boot up a Codespace and open my first Ruby file, I get the following two notifications:

command BUNDLE_GEMFILE=/workspaces/my-repo/.overcommit/Gemfile bundle exec rubocop returns empty output! please check configuration.
Source: ruby-rubocop

/bin/sh: 1: bundle: not found
Source: ruby-rubocop

In the VS Code Web Console, I see the following Javascript warning at the same time, although I don't know if it is related.

languageConfigurationExtensionPoint.ts:457 [ruby]: language configuration: expected indentationRules.increaseIndentPattern to be a string or an object.

From my devcontainer.json file, I have the following VS Code settings specified:

{
  // Other settings omitted 
  "vscode": {
    "settings": {
      "eslint.workingDirectories": [
        {
          "mode": "auto"
        }
      ],
      "eslint.useESLintClass": true,
      "eslint.validate": [
        "javascript",
        "vue"
      ],
      "files.insertFinalNewline": true,
      "files.trimFinalNewlines": true,
      "files.trimTrailingWhitespace": true,
      "ruby.rubocop.executePath": "BUNDLE_GEMFILE=/workspaces/my-repo/.overcommit/Gemfile bundle exec ",
      "ruby.rubocop.useBundler": true,
      "rubyLsp.rubyVersionManager": {
          "identifier": "auto"
      },
      "rubyLsp.bundleGemfile": "/workspaces/my-repo/.devcontainer/engineering/tools/lsp/Gemfile"
    },
    "extensions": [
      "dbaeumer.vscode-eslint",
      "github.codespaces",
      "github.copilot",
      "github.copilot-chat",
      "hashicorp.terraform",
      "misogi.ruby-rubocop",
      "ms-vscode-remote.remote-containers",
      "ms-azuretools.vscode-docker",
      "shopify.ruby-lsp",
      "vue.volar"
    ]
  }
}

From /workspaces/my-repo, I've tried running the command (below) myself and although it takes a little bit of time, it does eventually start outputting Rubocop violations as expected. I'm wondering if the plugin is timing out waiting for the command to run initially so it sees "empty output".

BUNDLE_GEMFILE=/workspaces/my-repo/.overcommit/Gemfile bundle exec rubocop

Goal

My goal here is to run Rubocop with Bundler, and use a non-standard location for the Gemfile. I do not want to use the default Rubocop that is in the PATH. Is this the correct way to configure this? If it is correct, is there a way to fix this warning?
