[BUG] - Cannot hit breakpoints with ng serve if Node 18 LTS is used #24601

Command

serve

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

Node 16 LTS

Description

When using Node 18 (LTS), a newly created project cannot hit any breakpoints (greyed out). The debugger gets attached correctly, but in VSCode no breakpoints are active. When downgrading to Node 16 (LTS), everything works out of the box as it should be.

You can make Node 18 work by adding --host=127.0.0.1 to the ng serve command. Then breakpoints get hit. I feel, one should not need to do this on newly creatd projects with the CLI.

Does not seem to be an issue directly with the CLI but maybe dev-server or Node itself, but it definitely affects CLI and the default projects are therefor broken (cannot be debugged).

Minimal Reproduction

Not working:

• ng new BreakTest (no routing, SCSS styles)
• Add breakpoint in app.component.ts line 9 (or any other valid line in any source file)
• Start debugging in Chrome

Working:

• ng new BreakTest (no routing, SCSS styles)
• Add breakpoint in app.component.ts line 9 (or any other valid line in any source file)
• In package.json add --host=127.0.0.1 to ng serve command
• Start debugging in Chrome

Exception or Error

All breakpoints are greyed out and do not get hit with Node 18
