Able to run tests, but not debug

[thomthom]

Your environment

• vscode-ruby-test-adapter version:
• Ruby version: ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x64-mingw32]
• VS Code version: 1.67.0
• Operating System: Windows 11 21H2
• Minitest version: 5.15.0

settiongs.json

{
  "solargraph.diagnostics": true,
  // https://github.com/connorshea/vscode-ruby-test-adapter/issues/86#issue-1064452536
  "rubyTestExplorer.debugCommand": "bundle exec rdebug-ide -I src -I tests/standalone/helpers",
  "rubyTestExplorer.minitestCommand": "bundle exec rake -I src -I tests/standalone/helpers",
  "rubyTestExplorer.minitestDirectory": "./tests/standalone",
  "rubyTestExplorer.logpanel": true,
  // As of VSCode 1.59 there is now a native Test Explorer UI.
  // "testExplorer.useNativeTesting": true
}

Expected behavior

I was expecting the selected test to run with the debugger attached.

Actual behavior

When I try to debug a failed test from the Test Explorer I get the following errors in the Developer Console instead of the debugger breaking at my breakpoints:

I'm not sure what kind of JSON input it's complaining about. Any ideas of what is going on or what I can do to get more insight to what's going on?

I think I figured this one out; I had to add debase and ruby-debug-ide gems to my Gemfile:

group :development do
  gem 'debase', '~> 0.2'         # VSCode debugging
  gem 'ruby-debug-ide', '~> 0.7' # VSCode debugging
  gem 'solargraph'               # VSCode IDE support
end
