Vscode-ruby: Breakpoint not hit for rails

[leaveofabsence]

Your environment

• vscode-ruby version: 0.12.1
• Ruby version: 1.9.3p551
• VS Code version: April 2017 (version 1.12)
• Operating System: OSX 10.12
• Hardware (optional): Macbook Pro 2015 x86_64

Have installed ruby-debug-base19x (0.11.31), ruby-debug-ide (0.6.0)
launch.config:
{
"name": "Rails server",
"type": "Ruby",
"request": "launch",
"cwd": "${workspaceRoot}",
"pathToBundler": "/Users/leaveofabsence/.rvm/gems/ruby-1.9.3-p551@sampleapp2/bin/bundler",
"useBundler": true,
"showDebuggerOutput": true,
"program": "${workspaceRoot}/bin/rails",
"args": [
"server"
]
},

Expected behavior

Breakpoints should be hit when debugging rails

Actual behavior

Debugger launches correctly and rails server is up and running. However, breakpoints don't activate (ie. breakpoint in UsersController.rb "index" action and navigate to localhost:3000/users, VSCode does not break on breakpoint). If I debug a simple .rb file using default "Debug local file" configuration, then breakpoints successfully activate.

This is the output from the Debug Console:

Fast Debugger (ruby-debug-ide 0.6.0, ruby-debug-base19x 0.11.31, file filtering is not supported) listens on 127.0.0.1:1234
DEPRECATION WARNING:

Any ideas of where I'm going wrong?

In my case I solved with bundle install --binstubs

I'm having same issue, @mberrueta 's suggestion did not make any difference for me.

Also having this problem. Not very experienced with VSCode debugger, but I've set breakpoints and the server does not stop.

Config:

    {
      "name": "Launch unicorn",
      "type": "Ruby",
      "request": "launch",
      "cwd": "${workspaceRoot}",
      "showDebuggerOutput": true,
      "program": "${workspaceRoot}/bin/unicorn",
      "args": ["-p", "3000", "-c", "./config/unicorn.rb"]
    },

Debug output:

Any updates here?

I actually managed to make it work by adding the path to my RdebugIDE

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Rails server",
            "type": "Ruby",
            "request": "launch",
            "cwd": "${workspaceRoot}",
            "remoteWorkspaceRoot": "${workspaceRoot}",
            "showDebuggerOutput": true,
            "program": "${workspaceRoot}/bin/unicorn",
            "args": ["-p", "3000", "-c", "./config/unicorn.rb"],
            "pathToRDebugIDE": "/Users/Etienne/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/ruby-debug-ide-0.6.0/bin/rdebug-ide"
        }
]}

My debug output shows

Fast Debugger (ruby-debug-ide 0.6.1.beta9, debase 0.2.2.beta10, file filtering is supported) listens on 127.0.0.1:1234

Closing for issue cleanup. Apologies if this is still an issue. We are working to improve the core extension experience.

For anyone who still has the issue, this config helped me:

 {
            "name": "Rails server",
            "type": "Ruby",
            "request": "launch",
            "showDebuggerOutput": true,
            "cwd": "${workspaceRoot}",
            "program": "script/rails",
            "args": ["server"]
 }

With original config on my project, startup script (${workspaceRoot}/bin/rails) executes 'script/rails' in the second process without the debugger.

In my case it was due to this:

https://github.com/Shopify/bootsnap/issues/168

I upgraded from ruby 2.5.3 to 2.6.0 and it fixed it (patching 2.5.3 to the latest probably would have worked too).
