Version

v23.2.0

Platform

Microsoft Windows NT 10.0.19045.0 x64

Subsystem

Node.js Debugger (V8 Inspector)

What steps will reproduce the bug?

Install Node.js v23.2.0

Create a simple JavaScript file:

test() {
    console.log("test");
    console.log("test2");
}
test();

• Set breakpoints in VS Code
• Start debugging session using VS Code's built-in JavaScript debugger
• Observe that breakpoints are not hit

How often does it reproduce? Is there a required condition?

Reproduces 100% of the time with Node.js v23.2.0. Issue does not occur with v23.1.0.

What is the expected behavior? Why is that the expected behavior?

Debugger should pause execution at set breakpoints, allowing inspection of program state.

What do you see instead?

Program runs without stopping at breakpoints. Breakpoints appear hollow/unfilled in VS Code, indicating they are not binding to the code.

Additional information

• Downgrading to Node.js v23.1.0 resolves the issue
• Using standard VS Code debugging configuration:

{
    "type": "node",
    "request": "launch",
    "name": "Debug Program",
    "skipFiles": ["<node_internals>/**"],
    "program": "${workspaceFolder}/test.js"
}
