Vscode-js-debug: Unbound breakpoint in VS Code when serving a different configuration

[jaadh]

Describe the bug

My issue

I have an Angular application that I am trying to debug in VS Code.

Currently when I serve the application e.g. ng serve my breakpoints are bound and the breakpoints get hit:

However, when I serve via a different configuration e.g. ng serve -c qa or ng serve -c uat the breakpoints become unbound:

Is there a reason why the breakpoints become unbound? How can I get the breakpoints to hit when serving with different environment configurations?

To Reproduce
Steps to reproduce the behavior:

1. Set a breakpoint in a .ts file where the breakpoint, in theory, should be bound
2. ng serve -c ENVIRONMENT
3. Observe that the breakpoint becomes unbound

I see that you have "sourceMap": false,. Without sourcemaps we cannot map source location to their compiled locations, or vise versa. Let us know if you have any other issues.

Thanks, I should have spotted that, sorry to waste your time.
