I am trying to debug a next.js 14.2.2 app with vs code. I have set the following launch.json file in accordance with the nextjs docs: https://nextjs.org/docs/pages/building-your-application/configuring/debugging

When I select full stack debug and hit F5 the debugger does not start. It fails with the following error:

C:\Program Files\nodejs\node.exe --inspect .....\node_modules.bin\next
Uncaught SyntaxError C:{MY PROJECT DIRECTORY}\node_modules.bin\next:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\,/,g')")
^^^^^^^

SyntaxError: missing ) after argument list

Process exited with code 1

So it looks like there is an issue with the next file that is in node_modules? Can anyone help me reslove this. All of the tutorials I've seen online has everything just working with no issues.

try maybe deleting node_modules and running npm install again.

Tried. No luck.

I believe the issue is that the launch.json that next provides is incorrect. They are clearly trying to run a bash script in node which makes no sense. Can anyone please povide a working launch.json?

@Cape lion try this, it worked for me:
{
  "name": "Next.js: debug full stack",
  "type": "node-terminal",
  "request": "launch",
  "command": "npm run dev",
  "cwd": "${workspaceFolder}", //you may need to change this to the root of your project
  "serverReadyAction": {
    "pattern": "started server on .+, url: (https?://.+)",
    "uriFormat": "%s",
    "action": "debugWithChrome"
  }
}

Thanks. That seems to work. They should update the docks.

I agree, I found that by using the wayback machine to search the docs for an earlier version of the launch config
