New Roblox Update Error (Promise340)

9reeze · July 31, 2023, 9:43pm

I got a random error out of the script called “Promise340”, which doesn’t exist in my game. It’s in CoreGUI where I can’t access it all, and I was wondering how to fix it. Here’s the error:

Unhandled Promise rejection:

I don’t think this error is fixable. I think it’s just a typical Roblox error that isn’t your fault, but the actual game is experiencing the error. This shouldn’t be too worrisome for you, as these errors aren’t usually going to damage anything in your game. It’s just the current Roblox server is experiencing some technical difficulties, and you most likely won’t see it again after retesting the game and such.

I have randomly just gotten this as well. I think this is a current Roblox server issue happening to everyone. Or its intentional.

what is roblox up to these days

OtterCarbonara · August 1, 2023, 1:01am

I think this an issue with Roblox’s code. Looks like it could be with the face tracking thing they’re doing. Nothing you can do about it, should get fixed soon I hope.

AkroThorn · August 1, 2023, 1:04am

I’m using a custom StarterCharacter and this isn’t happening, that’s pretty likely.

Maelstorm_1973 · August 1, 2023, 7:28am

Yeah. I just started seeing this myself. I think it’s a programming error in core scripts. The problem is the first line after the Promise.Error line (Looks like Line 4): attempt to index nil with FindFirstChild.

Time to file another bug report.

EDIT: Bug report filed. I’ll post the link when bug support approves it.

It doesn’t really harm to your game that much, i’ve also saw this error but however it didn’t made my game work that badly, so, it’s probably the Roblox is experiences technical issue somewhere.
So you don’t have to worry about it.

Yesterday I also got this error:

Face Chat Selfie View and Get Cam Mic Permissions.

Yeah, it’s pretty obvious what this is about lol

mineblox_jack · August 1, 2023, 6:18pm

fr i thought i was the only one with this error. hope this gets fixed

GAVsi115 · August 2, 2023, 10:03am

I think it has something to do with these settings:

CaelmDev · August 2, 2023, 2:55pm

the thing is that even though they are disabled it still shows up with the error for some reaso

faze_paspro · August 2, 2023, 3:05pm

I am also having this issue when playtesting my game

9reeze · August 2, 2023, 7:47pm

Even if you enable those settings, it still pops up the error.

SheepproIsHere · August 2, 2023, 8:59pm

i have same issue and its still happening to this day someone tell roblox to fix this

MrSonic2746 · August 3, 2023, 11:33am

I now understand what Roblox is currently working on lol

GAVsi115 · August 3, 2023, 7:09pm

What is most interesting, there is no such error on a PC, but on a laptop it is constantly.
The difference is that on a laptop I have buttons to physically disable the camera and microphone, but on a PC they are always on.

JoyfulFlowerMary · August 3, 2023, 7:50pm

Roblox’s developers didn’t completely test their new camera-based facial animation feature’s code on enough devices.

I think the error log analytics section shouldn’t show CoreGui and CoreScript errors, since the developer can’t fix any code there, even if they wanted to.

Katastro5 · August 4, 2023, 12:16am

Hello @9reeze! I also have the same error on my Roblox Studio with the latest Roblox Studio update. If you find a solution, please let me know! Thank you so much!

Sincerely,
@Katastro5

Katastro5 · August 4, 2023, 4:00pm

I am experiencing the same error, and to be honest, it broke my game and, to be more specific, my main local script. The new Roblox Studio bug is not letting me develop my Roblox game.
