Really Weird Bug Parent a Nil Value?

Help and Feedback Scripting Support
#1

I found a weird bug. Here is how I found it. First, I imported the same GUIs and scripts from my other place where everything worked fine and now for some reason, I am now getting an error:

 `Players.iNoobe_yt.PlayerGui.MenuGui.Menus.Worlds.Info.TeleportHandler:9: attempt to index field 'Parent' (a nil value)

Even though I get this error the script seems to be running fine in-game, however, I would still like to get it fixed. Here is the hierarchy and the line of the script where the error occurs:

From what I see “Info” is located inside of “Worlds”, not “Header Content”.

There is a TextLabel located in “Header Content” called Info.

You should show the contents of “Header Content”.

#5

Show the inside of that as well then, because there’s nothing to see.

Can you show the same Gui when you play the game in explorer?

This photo is taken in-game

Oh sorry, I’m a bit tired, did you try renaming the header?

#10

Still getting the error :confused:

This is one reason why you should populate your UI with scripts instead of physical instances. For example, you could be using Roact and avoid this whole “nil parent” problem altogether because you’re not having to either wait for instances or locate instances in a giant mess of UI that you’ve created.

Then again, this is just my opinion.

#12

Could you explain more? Populate UI with scripts? What do you mean by physical instances?

#13

You’re currently using a bunch of GUI instances to make your UI (which is fine in most cases), I’m just saying using a script to manage your UI could solve your problem as all of your references would be in your codebase. Roact provides a great framework for UI on Roblox; it’s straightforward, lightweight, and draws from concepts of React.js.

You also don’t even have to use Roact, you could just manually jot in GUI elements if you wanted.

#14

Try printing things out systematically. print(script) print(script.Parent) print(script.Parent.Parent) …etc
Also, try swaping bracketed indexing with :WaitForChild()

#15

Maybe the frame isn’t loading in time for the LocalScript to call “Parent”, hence the error calling it nil.

#16

I’ll look into Roact for my next project, but right now I am looking for a fix for this(there should be one)

#17

As @AbiZinho stated, maybe you should try using the :WaitForChild() method.

#18

Try adding like a wait(2) or something before you state the variable so you can test out if this is the case or not.

#19

How would I use WaitForChild on the parent?

#20

I added a wait(1), but it still errors
