SourceActorProxy Error on Setting Breakpoints

[gilmorem560]

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!
