Strange CoreGui Warning

[Kittylitterking123]

So whenever I hopped into studio this morning and playtested my game, the output was spammed with THIS:

 Unhandled Promise rejection:

-- Promise.Error(ExecutionError) --
CoreGui.RobloxGui.CoreScripts/FaceChatSelfieView:281: attempt to index nil with 'FindFirstChild'
CoreGui.RobloxGui.CoreScripts/FaceChatSelfieView:281 function updateSelfViewButtonVisibility

Promise created at:

Does anyone know what it means? Also, if this is in the wrong category, let me know. Have a wonderful day!

I’ve been getting the same exact thing, but it deletes all my parts in workspace and I’ve
tried fixing it multiple times with no success in any way.

My best idea is the Core Gui Scripts is messing up The Parts in Workspace

If you are able to locate where the scripts are at and what their names are I Might be able to fix it

[Kittylitterking123]

I can’t locate it, per se. But whenever I click on the text, an empty module script opens up and it’s named Promise340. I played my game to see if I could find in any of the services, but I couldn’t. But whenever I stopped the game, the output cleared itself and now it’s gone.

[Developing_Scripter]

If you click on the error and stop the game

When running you can have access to the Promise340 code, and it seems that it is empty.
Try adding this to the Module Script code.

I think this is Roblox Fault and Not our Fault.

[Gingeeeers]

maybe it ocurrs when roblox wants to access our camera and the device doesnt have one

@Developing_Scripter

I think this is Roblox Fault and Not our Fault.

it is

[Developing_Scripter]

The code is empty.
And second of all Is a Core Gui issue not something I added into studio.
It Has To have something to do with something on Roblox’s end.

[Kittylitterking123]

Sometimes it shows up in my output and sometimes it doesn’t. It’s weird.

@Gingeeeers I think you are right. The warning is stemmed from the new camera update Roblox recently dropped.

I’ve sent @Bug-Support a message about this a couple days ago. I expect a fix soon.

Also, since it’s a CoreScripts bug, we are able to do literally nothing about it. Fun, right?

Hello @Kittylitterking123!
I have the same bug in my Roblox game, and it ruined my local scripts.
Please let me know if you find any solutions on how to fix this bug!
Sincerely,
@Katastro5

It wasn’t a bug report, I don’t have access. I sent a message to @Bug-Support about it.

I will let you know if they get back to me though.

[Katastro5 (Kat)]

Hello @Fizzitix!
Thank you so much!
Sincerely,
@Katastro5

They have just responded.

Someone made a bug report about it just 6 minutes ago:

Warning intermittently prints in output about a rejected promise in core scripts when playtesting

I have seen this error and I’ve reported in the tread from the new animate your avatar with your movement where this error coming from

Animate your Avatar with your movement

I think there is an bug with this new function [Screenshot_20230803_134940_Chrome]

But now the massage is longer then first

[Kittylitterking123]

Whenever you click on the wanring, an empty Module Script named Promise340 appears. Like @Developing_Scripter said, type script:Remove() in it. It worked for me until I logged back on. It should still work for the moment. Let me know if this helped!

To see CoreGui, look at this post i made a while ago:

New Roblox Update Error (Promise340)

Hi Everyone, so i also have the same problem and i think its a problem handling with the permission for Face View and VC. You can access Core Gui In studio settings if u want to see the script itself (Pretty much useless since its empty). I believe theres actually no way to fix this and also this error may only come for people with VC (I Think) [Screenshot_1]
