Long "Unhandled Promise Rejection" warning gets spammed in my playtest outputs

[DataBrain (Amber)]

Reproduction Steps
This warning prints in my output every time I run a playtest in studio:

My computer:

This happens both on play solo tests, and on player + server tests in the client-side output.

Edit: This also happens in live servers of my places

I develop with an “unreliable and slow internet connection”, if that should matter at all.

Another user posted about this: Unhandled promise rejection

Apparently publishing the game fixed the issue for them? For me, I see this both in (non-team-create) published games and in published/saved team create games.

Expected Behavior
This should fail silently instead of spamming the output every playtest.

why is there a character limit for this part of the bug report wizard

Actual Behavior
A very long warning appears in the console for a core script that I shouldn’t know about.

A private message is associated with this bug report

Edit: This issue seems to be caused by the core scripts not handling empty descriptions correctly, as discovered by @GolgiToad, so adding a description to your place seems to be a functional workaround to this issue.

Do you have Social Service’s Invite feature in your game? Because, similar thing happens if you use it.

[DataBrain (Amber)]

I do, but this warning appears immediately whenever I join the game on my client, regardless of whether I actually send out invites.

I squashed this promise error…

Read it closely…

(drum roll)

Your game doesnt have a description and or name…

this has also happened to me but it hasn’t effect anything on my game

I can reproduce it on my windows PC, and my pc specs are overkill so i dont think that can be the issue.

[GolgiToad]

Check your game settings. If your description is empty, put something in. I havent seen the error since.

[anirudh851 (Ani)]

Hmmm, @DataBrain you should mark this as a workaround, this stops happening after u put a description.

[DataBrain (Amber)]

Looks like adding a description to my places worked in getting rid of the error.

Regardless, this is a bug that roblox should fix on their end.

@anirudh851 already one step ahead of you!
