vscode: When launching a webapp debugging session on an non-mainstream browser, VSCode errors providing no useful info

Does this issue occur when all extensions are disabled?: Yes, as I haven’t installed any.

• VS Code Version: 1.72.0
• OS Version: ArchLinux, up-to-date

Steps to Reproduce:

1. Install qutebrowser
2. Use the following as the your launch.json when debugging a web app, and you’ll get an “Unable to attach to browser” error message. Unfortunately such an error gives no info (at least I couldn’t find it) to investigate the problem further, should it be on qutebrowser’s side

   {
       "version": "0.2.0",
       "configurations": [
           {
               "type": "chrome",
               "request": "launch",
               "runtimeExecutable": "/usr/bin/qutebrowser",
               "runtimeArgs": ["-T", "--qt-flag remote-debugging-port=9229"],
               "name": "Launch Chrome against localhost",
               "url": "http://localhost:1234",
               "webRoot": "${workspaceFolder}"
           }
       ]
   }
