Instant crash when accessing navigator.getUserMedia

[loadpixels]

Attempting to access the camera or microphone either through code or the console will result in the chrome instance crashing

• VS Code Version: 1.43.0
• Chrome Version 80
• Log file (set "trace": true in launch config):

Steps to reproduce:

1. Start a Chrome instance using VS Code Chrome Debug
2. Open console and paste in this line: navigator.getUserMedia({video:true},devices=>{console.log('hello')},err=>{console.log(err)})
3. Allow access to the camera
4. Chrome will crash without a trace

• old debug adapter: crash
• chrome devtools: works
• js-debug: I don't get the prompt from Chrome for camera access

This works for me in js-debug. Did you previously deny camera access on localhost:N? That would prevent it from prompting again.

[roblourens]

Maybe, I changed the url to google.com and then I get the crash with js-debug too.

[connor4312]

hm, still works for me there. Can you or loadpixels get a trace log?

[roblourens]

The log shows a normal launch then disconnection, I don't think there's anything interesting. I tried with "userDataDir": false, setting a port to use that instead of the debug pipe, and commenting out all the flags we set when we spawn Chrome.

One thing I noticed, if I start Chrome from the terminal and do this, then after I click Allow, I get a macOS prompt to allow iTerm access to the camera. So maybe vscode/Electron doesn't want to allow access to the camera.

@loadpixels what OS are you on?

[loadpixels]

@roblourens MacOS

echoing @connor4312 there's no tracelog to speak of, it just crashes

it happens as soon as I click the Allow button on the permissions dialog

I experience the same problem. MacOS. I accept camera, and chrome immediately exits. Under VS Code debug only, works well in browser.

[roblourens]

You can use an "attach" type config to work around this. I don't have anything better, sorry.

Doesn't seem to happen on Windows. Tracking upstream with: https://bugs.chromium.org/p/chromium/issues/detail?id=1066155
