Breakpoints become unbound immediately upon attaching to nodejs process

[jschank]

I am trying to debug a nestjs application, written in typescript. And I am attempting to attach to the process, so I can hit breakpoints.
The breakpoints become unbound immediately upon attaching to the process.

Here is the trace file
vscode-debugadapter-cb19f722.json.gz

Here is my Launch.json

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Attach to Nest",
      "type": "node",
      "request": "attach",
      "port": 9229,
      "restart": true,
      "skipFiles": [
        "<node_internals>/**"
      ],
      "trace": true,
    }
  ]
}

I know the debugger is attaching to the process because I see this emitted in the console

Debugger listening on ws://localhost:9229/d8180938-a9d6-46d8-81a3-814a66b98348
Debugger listening on ws://localhost:9229/d8180938-a9d6-46d8-81a3-814a66b98348
For help, see: https://nodejs.org/en/docs/inspector
Debugger attached.

My angular.json file has this...

"serve": {
    "configurations: {
            "dev": {
              "buildTarget": "nest:build:dev",
              "inspect": true,
              "port": 9229
            }
    }
}

Any help is appreciated, I've googled unbound breakpoints, and tried many things. None of which made any difference.

Thanks,
John Schank

It looks like you should set "cwd": "${workspaceFolder}/workspace". Nest.js provides Webpack paths, which are relative, so we need to know where to resolve them from. In your case, it looks like you have it in a nested directory, which requires this adjustment.

Connor, your advice was spot on, and solved the problem. I've seen you reply to lots of other issues as well, in my search for an answer to my particular problem.

Can you clue me into how you solved it so quickly? None of the resources I found online mentioned that property.

In any case, I really appreciate your swift response. (they don't pay you enough)

I saw that you set a breakpoint in

/Users/jschank/Mobius/mobius-repo/workspace/apps/nest/src/app/trm/merge-utility/trm-merge-utility-software-governance.controller.ts

And then this line of the log file:

"SourceMap: mapping webpack:///./apps/nest/src/app/trm/merge-utility/trm-merge-utility-software-governance.controller.ts =>
/Users/jschank/Mobius/mobius-repo/./apps/nest/src/app/trm/merge-utility/trm-merge-utility-software-governance.controller.ts, via sourceMapPathOverrides entry - /^webpack:\\/\\/.*?\\/(.*?)$/i"

showed me that the folder was missing.

I want to improve the setup experience: #1214
