I have configured my Visual studio code to debug nodejs, chrome(vuejs) application using the recipe in the link. I am however getting a "Failed to exec debug script" error when I debug "Meteor All" error in visual studio code. If I add a breakpoint in the server side code I see a "breakpoint set but not yet bound". I am however able to debug client side code correctly. What am I missing?

Launch.json in visual studio code:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "chrome",

        },
        {

I just use --inspect, and it works fine.

I have not had success specifying the port with --inspect-brk=9229

--inspect uses port 9229 anyway

Your config for the server should be like this:

{
  "type": "node",
  "request": "attach",
  "name": "server",
  "restart": true,
  "port": 9229
},

The restart option is useful while you are editing code, as it survives server restarts (by re-attaching)

It seems this message shows up if the debugger cannot "reach" the breakpoint's file through the node process the debugger is attached to.

The error message is not well covered in VS Code documentation so it's hard to find out what causes it.

I tested this by adding a file to a project, putting a breakpoint in it but not include/require'ing it anywhere. When you run the debugger (on another file) the breakpoint you just added will be "set but not yet bound". Conversely, if you include/require the new file, the breakpoint will be normal (even if your tests never reach the line the breakpoint is on).

In my case, I inherited a codebase and found out that if your script spawns child processes (e.g. through child_process.execFile), the debugger will not track the code in the child process. Instead, it will show breakpoints as "breakpoint set but not yet bound".
