I’m using VSCode 1.61.1 on Mac Big Sur with a Rails 4.2 application (ruby-debug-ide 0.7.3, debase 0.2.2.beta10), running with a Unicorn app server. The Rails app runs on a virtual server (built through Vagrant). I have exposed all the necessary ports. I have this configured in my launch.json
"configurations": [
{
"name": "Listen for rdebug-ide",
"type": "Ruby",
"request": "attach",
"cwd": "${workspaceRoot}",
"remoteHost": "127.0.0.1",
"remotePort": "1234",
"remoteWorkspaceRoot": "/home/my-app",
"showDebuggerOutput": true
},
Then in my virtual server, I start Rails using
rdebug-ide --debug --host 0.0.0.0 --port 1234 -- bin/rails s -p 3000 -b 0.0.0.0
From VS Code, I then attach the debugger by clicking on
On my Rails server, I can see this debug output

Then from VSCode, when I add a breakpoint, I see this output on my Rails app
15:09:16 rails.1 | 5360: Processing in control: break /home/my-app/app/controllers/api/v1/products_controller.rb:10
15:09:16 rails.1 | 5360: <breakpointAdded no="1" location="/home/my-app/app/controllers/api/v1/products_controller.rb:10"/>
But then when I actually visit the web page that is supposed to hit the breakpoint, nothing happens. I now the code is called because I see “print” statements output to the log. But not sure what else I need to do to get VSCode’s debugger to engage at the appropriate breakpoint.
