SourceActorProxy Error on Setting Breakpoints

Reproduce the breakpoint failure using the posted launch.json configuration against the Angular application, then start with the SourceMappingSourceActorProxy and SourceActorProxy log entries around getBreakpointPositionsCompressed. Done means setting a breakpoint from VS Code no longer produces the noSuchActor error and the breakpoint can be hit.

Hello, I'm having a repeat problem lately when trying to use this extension to debug an Angular 14 application in VSCode.

My OS is macOS 12.5.1 (x86_64)
Browser is Firefox Developer Edition 105.0b2
VSCode Version is 1.70.2
Extension Version is 2.9.8
Angular Version 14.0.5

I find that any time I set a breakpoint in a file while I have Firefox debugging started, I receive something to the effect of:

DEBUG|044.875|BreakpointsManager: Setting 1 breakpoints for /path/to/src/app/app.component.ts
DEBUG|044.876|SourceAdapter: Going to delete 0 breakpoints

ERROR|049.079|SourceActorProxy: No such actor "server1.conn0.child10/source26"

My launch.json config is:

{
    "name": "Build then Launch Firefox",
    "request": "launch",
    "type": "firefox",
    "url": "http://localhost:4200/",
    "webRoot": "${workspaceFolder}",
    "preLaunchTask": "npm: starthot",
    "log": {
        "fileName": "${workspaceFolder}/vscode-firefox-debug.log",
        "fileLevel": {
            "default": "Debug"
        }
    }
}

where npm: starthot is simply a wrapper for ng serve with the specific configuration we use for debugging supplied.

It seems the error is that the server1.conn0.child10/source26 actor does not exist. I've verified that the various under-the-hood settings in about:config are matching and we're using the default debugging ports. I can confirm that launch does start Firefox in remote control mode evidenced by the red-striped URL with a little robot, and if I open the devtools in the browser itself, I can navigate to the Webpack sources in the current thread, set breakpoints, and they are even hit in the browser console, but the breakpointing connection between VSCode/the extension and the browser seems to be getting stuck.

Any ideas or suggestions? Let me know if any further info is needed. Thank you!
