Request Agreement

• I have searched the existing issues and found no similar issue
• I am using the latest Vesktop and Vencord versions
• This issue occurs on an official release (not just the AUR or Nix packages)

[EddoWagt]

Can confirm, same happens for me on fedora, wayland using flatpak

[Curve]

Notably does not happen to me on KDE 6.1.2 (Arch Linux), promise rejection also occurs but no crash

[FruitBoi]

Happening for me as well on wayland KDE 6.1.2 (gentoo) in flatpak

[Vendicated]

can reproduce but probably not fixable by us. we changed nothing about the code, we just upgraded chrome / electron, so it's likely a regression in those

I'm getting the same issue but in my case it's not when dismissing the request, it's when clicking the screenshare button. It just crashes and leaves the same error message in the console.

I'm on EndeavourOS with Sway, installed it through pacman.

[Daxanius]

It looks like screenshare does not work for me even in older versions. It pops the error UnhandledPromiseRejectionWarning: TypeError: Video was requested, but no video stream was provided but this time without crashing. So it seems in the latest version the error gets popped, the screenshare request gets dismissed automatically, which in turn causes the crash.

[kubni]

Same behaviour. I had that UnhandledPromiseRejectionWarning for a while, and I can't screen share on Vesktop at all.
Recently, it started segfaulting after showing that same message.

[AvirukBasak]

Can confirm on Ubuntu 24.04, Wayland, navigator.userAgent gives Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36

[Covkie]

This is a regression with electron ^31.0.0

the UnhandledPromiseRejectionWarning: TypeError: Video was requested, but no video stream was provided error is unrelated to this crash (you can trigger it by dismissing the screenshare modal within discord itself without crashing).

Sorry for not finding this sooner. And last I checked, upstream doesn't care about bug reports unless you can write a minimal reproducer for them, since their development team is apparently as small as yours is.

[103sbavert]

Is there an Electron repo issue that is opened regarding the regression with electron? I can't seem to find it. If there's one, I'd like to read the discussion.

[Covkie]

@103sbavert I finally got around to reporting it 2 days before your comment :p electron/electron#45198

[103sbavert]

By the way, to the desktop team, you guys could easily fix this issue with the latest discord 0.80
