Cannot debug

[bholemaharaj]

Type: Bug

I am not sure which extension is causing this but when I started VS Code today and when I choose Javascript Debug Terminal, the breakpoints are not hit. I have tried everything to troubleshoot including re-installing VS Code.

VS Code version: Code 1.95.3 (f1a4fb1, 2024-11-13T14:50:04.152Z)
OS version: Windows_NT x64 10.0.22631

I have re-installed VS Code using VSCodeUserSetup-x64-1.95.3.exe, also renamed the extensions folder so I would have no extensions installed. Then, I installed JavaScript Debugger (Nightly) extension. Still, no break points are being hit.

[bholemaharaj]

Ok now I am hitting the break points but, here is what I had to do and not sure why since I never had to do it before.
Now besides using JavaScript Debug Terminal, I had to also use Debug: Attach to Node Process and attach a process from the list which I never had to do before. I also have following set in my settings.json file

"debug.javascript.terminalOptions": { "trace": true }
the output of that is

> npm run start-server
> runtime.launch Bootloader imported {
>   env: {
>     inspectorIpc: '\\\\.\\pipe\\node-cdp.23460-e80dd6e7-2.sock',

I have reset settings.json to default but debugging is not still not working.

[bholemaharaj]

Ok, here is something that might help, debugging started to work in VS Code, I uninstalled the node v23.3.0 and installed the current LTS version. Not sure if that fixed the issue. Something you may want to verify. Thanks.

[bholemaharaj]

While encountering the issues on my work machine, I verified that the problem stemmed from Node.js v23.3.0, which caused debugging to stop working in VS Code. To confirm this, I tested debugging on my personal Windows 11 machine using Node.js v23.3.0 and observed the same issue. After uninstalling v23.3.0 and installing the LTS version (v22.12.0), debugging started working as expected.
Hope this helps to further investigate why and what may be causing this issue.
Thanks.

I just tried a lot of launch configurations to solve this issue, and finally I found this! Thanks a lot!
